That is your lot for our European coverage for tonight. If you still have a taste for football, why not head over to our MLS Final live text commentary where Jonathan Jurejko is in charge and will let you know every time someone hits the score bag.
And there is the full-time whistle. It is a first defeat for David Moyes as Real Sociedad boss and a humbling one at that. His side had not conceded in three before tonight but they were picked apart way too easily once Villarreal got their act together in the final quarter. You are not a world beater after one win, nor are you a joke after one defeat, but Moyes now knows he has some work ahead of him.
Pina almost gets in on the action but his shot from the edge of the box is blocked by a diving Sociedad defender. Real Sociedad are just praying for the whistle now to put them out of their misery.
It should be five. Enaut Zubikarai produces a superb save to tip over Trigueros' shot from eight yards out. Sociedad are completely shot here. This is a big wake up call for Moyes.
A thoroughly deflated Sociedad make a final change as Sergio Canales departs and is replaced by Pablo Hervias.
Things go from bad to worse for David Moyes. This is getting embarrassing for Real Sociedad now. Mui Gomez has his second goal and he can thank away keeper Enaut Zubikarai, who allows his low shot from the edge of the box to find its way under his body and in. The keeper is not the only one to blame, though. Gomez was given an age to fire in his shot.
The home side's final change sees Bruno come off to a standing ovation. He has been very good to be fair. On comes Pina for the final six minutes.
The supplier of that last goal Denis Cheryshev departs and on comes Gerard Moreno. It is job done for the home side.
This is turning into a drubbing for Moyes' side now. Mui Gomez has only just come on but he immediately makes his presence felt by playing a ball out wide to Denis Cheryshev before charging into the box to fire home the low cross. Back to the drawing board for Dave - his side have been picked apart ruthlessly tonight.
OptaJose: 8 - Denis Cheryshev has been involved in more goals than any other Villarreal player in La Liga this season (2 goals, 6 assists). Gunboat.
Moyes makes a change of his own with an injured Zurutuza being replaced by Alfred Finnbogason.
Off goes Uche for Villarreal and on comes Moi Gomez. There are 15 minutes left for Moyes and his men to salvage an unlikely point.
And that should be that. Villarreal double their lead with a neat move that shifts the ball from a throw-in on the right to the left of the box via Luciano Vietto and Uche before Denis Cheryshev drives a low shot across the keeper and in to the bottom corner of the goal. David Moyes is staring his first La Liga defeat squarely in the face.
Luciano Vietto is justified in thinking the gods are against him tonight. He strikes a shot from range which beats the Sociedad keeper and hammers against the base of the post before deflecting away from danger.
Real Sociedad need to get a grip here. Uche drives forward into acres of space and is allowed to fire a low shot that flies just past the post.
Villarreal go close to making it 2-0 as Jonthan dos Santos finds space on the right to swing over a cross for Denis Cheryshev. Unfortunately for the home side, Cheryshev is unable to steer his volley on target. That would probably have buried Moyes' side.
That is what they can do with it! Bruno steps up and clips his shot over the wall and against the bar before the ball strikes the back of away keeper Enaut Zubikarai and into the net. I've put the goal down to Bruno but there is every chance that could go down as an own goal. Either way, Sociedad have conceded their first goal under David Moyes and they now have some work to do.
Here is a chance. Villarreal have a free-kick right on the edge of the box. What can they do with this?
Villarreal continue to press forward. Bruno tries a through-ball to Luciano Vietto in the box and it is just a tiny bit of weight away from perfection. Instead of reaching the striker it skips ahead of him and out of play.
Rian Hoskins: Sociedad have squad that is capable of a top six finish. What Moyes will do is make sure no-one has an easy game against them
Tom Crossman: As a United fan, Moyes has my full support. It may not have worked out at United, but he will always have my full support.
Tom Foolery: David Moyes should be angry at United, he was never trusted. Hope he does well
Some heart-warming support for Moyes. Tiny Tim would be proud of you. God bless us, everyone
Finally, a bit of excitement. Luciano Vietto shows some neat skill to weave into a shooting chance on the edge of the box but his effort is tipped over by Enaut Zubikarai. Soon after, the young striker has another opening and this time beats the keeper but not the post, which is struck on the inside, with the ball flying back out before being hammered clear.
Manuel Trigueros swings in the Villarreal corner but Socieded are back organised and are able to clear with relative ease.
Carlos Vela still looks lively for Sociedad. He has won a free-kick on the right side of the box for a shove in his back as he charged to the byline. Sergio Canales whips it in and Uche heads it away at the near post. Villarreal charge straight down the other end on the counter and win a corner...Copyright: EPA
Inigo Martinez is not a happy chap. He is forced to hammer the ball out to the far side in desperate fashion, mainly because he didn;t get a shout from a team-mate to tell him a Villarreal player was on his case. Six minutes gone in this half. Neither keeper has had a touch.
And now Inigo Martinez needs to be alert to cut out a low cross from Uche from the left.Copyright: EPA
Villarreal are on the attack early doors in the second half. Carlos Martinez is forced to dive in to halt a marauding run forward by Denis Cheryshev in the box.
We are up and running again in El Madrigal. Here's hoping we get a goal or two this half.
Phil Bayley: I'm supporting Villarreal and whoever else happens to be playing Sociedad all season. I'll never forgive Moyes for breaking Utd
You've got to let it go Phil. It's nearly Christmas time and the last thing you need is three ghosts keeping you awake on the 24th
In case you missed the earlier game, I can inform you that Lionel Messi made sure that Cristiano Ronaldo didn't take all the headlines this weekend with a hat-trick of his own as Barcelona beat local rivals Espanyol 5-1. It takes Barca back into second in La Liga and two points behind Ronaldo's Real Madrid.
David Moyes' team hang on to the break. It has not been a classic encounter by any stretch of the imagination, but Moyes will be happy that his side are still level in what is his biggest test to date as a La Liga boss. Villarreal were building up a head of steam towards the end of that half so the whistle will be welcome by the away side.
Sociedad are in survival mode now. Uche sets alarm bells ringing with a pass that deflects up to Denis Cheryshev in the box, but he fluffs his volley. Then the winger drives a low ball right across the box that flies just a yard ahead of a sliding team-mate near the penalty spot.
More fury from the home fans as Luciano Vietto is booked for a challenge on Inigo Martinez, which leaves the defender on the turf. They are right to be angry as well as Vietto won the ball and Martinez made a real meal of the situation. Baaaad form, Peter.
Villarreal are turning the screw a bit now. A couple of corners in succession pose a challenge for Real Sociedad but they do well to deal with both. You can see why Sociedad have yet to concede under Moyes. They are hard-working and well-drilled at the back. Inigo Martinez has flirted with disaster a couple of times, but beyond that it has been good stuff.
The resulting free-kick beats the wall but does not dip enough to go under the crossbar. Close but no cigar from Bruno.
Controversy! Luciano Vietto is through on goal after chesting a long ball forward past Inigo Martinez. The striker reaches the edge of the box and is about to pull the trigger before he is felled by a sliding tackle from Alberto De La Bella. The hoem crowd demand red, but it is a yellow card shown. The ref must have thought Ansotegi was able to get over and so De La Bella wasn't the last man.
Chaos in the Sociedad box as Jonathan dos Santos looks to nip the ball past a couple of challenges and into a shooting chance in the box. The ball deflects to Luciano Vietto but he is unable to get his shot on target. The stalemate continues.

Carlos Vela is the outlet for Real Sociedad. He uses his pace on the left to break into Villarreal territory before swinging over a superb cross, which almost reaches David Zurutuza in the middle. It ends up swinging a yard ahead of the Sociedad striker.
Carlos Vela wins his side a corner after a terrible back-pass from Denis Cheryshev. Unfortunately for Sociedad, the resulting set-piece is swung straight into the grateful arms of Sergio Asenjo in the home goal.
Darren Porter: Worth noting Moyes has previous with Villarreal, they ended Everton's dreams of reaching the Champs Lge Group Stage in 2005
Denis Cheryshev shows a superb touch to bring the ball down after it plummets in his direction from the sky. It gives him half a chance to get a shot on goal from inside the box but fails to generate enough power to beat Enaut Zubikarai.
Sociedad look to test Sergio Asenjo as Ruben Pardo swings a boot at a ball that deflects into his path. His effort takes a touch off a home player and goes behind but Sociedad are unable to make anything of the corner. It is not much but in the context of this tight game it counts as a decent chance.
John McEnerney: Canales is the key man for Moyes if he stays injury free, a top talent blighted by injury La Liga's very own Darren Anderton.
Bruno gives Sociedad some respite by sliding in to foul David Zurutuza. It gives the away side their first chance to move out of their own half for five or so minutes. They make nothing of it, though, as an ambitious ball from left to right is poorly-executed and cut out.
Villarreal are enjoying a good spell of pressure now after Sociedad's bright opening. The game is played largely in the away side's half and it is requiring some agricultural defending to clear. Vietto looks to make amends for his earlier miss but his square ball on the edge of the box is cut out and hammered away.
Best chance of the game so far goes to the home side, in what is their first real attack. The Sociedad defence makes a hash of a long ball forward, which is flicked on to Luciano Vietto, but instead of chipping the keeper (the only obstacle between him and the goal) he goes for power and blazes his effort way over the bar. It is an ugly finish.
Carlos Vela is in the wars here. He is hacked down again 30-odd yards from goal. It gives Sociedad another chance to swing in a free-kick, which they do but to little effect as the ball floats harmlessly over everyone and out to the far side for Villarreal to clear.
Moyes' side have started well here. A lovely forward pass releases Carlos Vela again and he is able to dig out a cross from the byline, but is unable to find a team-mate as Victor Ruiz's head makes the clearance.
Carlos Vela is in full flight down the right until he is floored by a cynical tackle. It gives Sociedad a free-kick, which Sergio Canales tries to cheekily swing inside the near post, but he misjudges it and puts it a few yards past the post.

It has been a pretty good start by David Moyes to his managerial redemption, with Sociedad unbeaten in three and yet to score a goal under his guidance. This is a big test tonight, though. Villarreal are a tough side on home turf and are eight points and seven places above Moyes' men in La Liga. Not much to report on the pitch yet in these early stages.
Villarreal: Asenjo, Gaspar, Costa, Ruiz, Paulista, Bruno, Dos Santos, Cheryshev, Trigueros, Uche, Vietto.
Real Sociedad: Zubikarai, Ansotegi, De La Bella, C. Martinez, I. Martinez, Prieto, Granero, Zurutuza, Pardo, Vela, Canales
Hello folks. Sorry to rush but we've no time to waste. We are under way in El Madrigal as David Moyes looks to preserve his unbeaten start to life with Real Sociedad. Here are your teams...
Lionel Messi and David Moyes are rarely uttered in the same breath - until now. We're switching from Messi's exploits to Moyes' reign at Real Sociedad, who are aiming to extend their La Liga unbeaten run under the Scot to three games.
And we're making a tactical switch of our own. Here's my team-mate Phil Dawkes to talk you through the action from El Madrigal.
So, thanks to Messi's treble, Barcelona earn the almost-expected bragging rights against poor relations Espanyol.Copyright: BBC
More importantly, it moves Luis Enrique's men back up into second place. They are two points adrift of Real Madrid and the emphatic nature of the victory closes, perhaps importantly, the goal difference gap on their arch rivals.
For 45 minutes, Barcelona looked poor. They lacked urgency, were devoid of attacking ideas, and had little defensive organisation. Then, Lionel Messi produced a moment of quality to nick a barely-deserved equaliser and they didn't look back.
All over in the Nou Camp! Espanyol's players breath a huge sigh of relief as they are put out of their Messi-induced misery.

Neymar is desperate to put his name on the scoresheet - like your Sunday League team's centre-half when you're winning 9-1 against a bare XI. He shuffles along the edge of the Espanyol area, but sees his shot blocked.
Two minutes of stoppage time. Espanyol wish there wasn't any.Copyright: Getty Images
OptaJose: Lionel Messi has scored his last nine goals for Barcelona from just 12 shots on target (all competitions).
Time for a sixth? The home fans certainly hope so as they bay for another goal. Barca surge forward again, but Espanyol scramble back to crowd out and dispossess Neymar in the danger zone.
Warning to Espanyol - you are one of three La Liga teams that Lionel Messi has scored four goals against. And the Spanish top-flight's record scorer looks hungrier than a prowling fox for another.
Never mind 12 minutes - Lionel Messi only needs three to complete his treble!
Pedro, perhaps with his ears ringing from his selfishness a few moments ago, tees up Messi after a slick one-two to slide in Barca's fifth. Magic.Copyright: Getty Images
Although Lionel Messi fails to break into a beaming smile as Barca celebrate that goal. He was waiting for a pull back from Pedro to tap in and complete his 21st La Liga hat-trick - two adrift of arch rival Cristiano Ronaldo, who broke that record last night.
Twelve minutes to get another match-ball...
Game. Set. Match. As if it was in any doubt.
Luis Suarez's replacement Pedro sticks his name on the scoresheet as Barcelona boost their goal difference in pursuit of rampant leaders Real Madrid.
The Spain star deftly controls Jordi Alba's raking pass, steadies himself and drills low into the bottom corner.
Of course, Luis Suarez does earn himself an assist for the pass that led to Lionel Messi's second goal - but that was all about the Argentine's brilliance.
OptaJose: Only Cristiano Ronaldo (7) has made more assists than Luis Suárez (5) since the Uruguayan player's La Liga debut.
Lionel Messi hoists the resulting set-piece over the Espanyol wall, but cannot hit his intended target. That effort is sandwiched in-between a switch for either side - Luis Suarez, who has not been as effective as he is remembered as being by Premier League fans, is replaced by Pedro.
And Espanyol's Felipe Caicedo goes off. The ex-Manchester City man was as effective as he is remembered as being by Premier League fans....
How do you stop Lionel Messi? Brutally clatter into him from behind is the method of choice from Espanyol defender Alvaro Gonzalez. Yellow card for him. And a Barca free-kick in an ominous position.
And that is Ivan Rakitic's last contribution. On comes Andres Iniesta to a hero's reception - it is his first La Liga appearance since September following a calf injury.
Pretty sure a World Cup-winner trotting on to the pitch is the last thing that the Espanyol players want to see now...
Barcelona are winning the ball higher up the pitch now - something which they failed to do in the first half. Ivan Rakitic spanks a vicious volley towards goal, but a blue and white Espanyol shirt bravely blocks. Bet that is what I call a 'cold Sunday morning stinger'.
What a difference a Lionel Messi goal or two makes. Barcelona are purring now. Xavi lofts forward a ball towards the rampaging run of Dani Alves, but the Brazilian does not have the legs to reach it and Espanyol clear.Copyright: AFP
Change for Espanyol as they attempt to claw a way back into this match. Or more likely attempt to limit the damage.
It's the latter. Definitely the latter. Experienced Mexico defender Hector Moreno enters the fray, in place of the more attack-minded midfielder Jose Canas.
About 15 minutes of football ago, Espanyol were in dreamland. Now they are waking up in the middle of the night, sweating and screaming about a Lionel Messi-inspired nightmare.
Barca have looked a totally different proposition since the break. Whether they have been boosted by Messi's equaliser on the stroke of half-time, or a tongue-lashing from boss Luis Enrique I'm not so sure. Maybe a little bit of both.
Game over, surely. Less than 150 seconds after Messi's second goal, team-mate Gerard Pique puts clear daylight between the neighbouring clubs. The Barca centre-back climbs above a static away defence to powerfully head in Ivan Rakitic's cross from a short corner.Copyright: Getty Images
Guess who? Yes. Lionel Messi puts Barcelona ahead for the first time this evening, drilling in a right-foot shot from 20 yards.
The Barca hero takes a heavy touch (seriously) as he controls Luis Suarez's pass, before recovering with a magical second, dinking it through a defender's legs, before smashing in a low strike with his weaker foot.Copyright: Reuters
The white handkerchiefs are out at the Nou Camp. They are being waved by the home fans - a sign of their disgust - at the referee, who decides Espanyol defender Eric Bailly's robust shoulder charge on Neymar is legal.
And within seconds of the kick-off, Barcelona win a free kick in a dangerous position. Xavi whips in an in-swinger from a right-central position but the tall frame of Gerard Pique is three inches too short to connect with a stretching leg.Copyright: EPA
No changes at the break for either side. Espanyol, backed by less than 100 fans inside the Nou Camp, restart the action.
OptaJose: 200 - Lionel Messi has scored his 200th La Liga goal since Cristiano Ronaldo's arrival to Real Madrid (2009/10). Rivalry.
The other concern for Luis Enrique is that a below-par performance does not bode well ahead of their big Champions League clash against Paris St-Germain in midweek.
The French champions need at least a draw at the Nou Camp to finish as group winners - and therefore leaving already-qualified Barca with the prospect of a tough last-16 tie.
If this scoreline stays the same then Barcelona will move back into second place - above defending champions Atletico Madrid - courtesy of their better goal difference.
But they will slip four points behind leaders Real Madrid after 14 matches.
But I suspect that won't drastically improve the mood inside the Barca dressing room as they tuck into their half-time oranges. Luis Enrique's men have been poor and they can't afford to drop points against an Espanyol side loitering in the bottom half.
I said Barcelona needed some Lionel Messi magic - and it has arrived! The Argentine superstar creates a yard of space for himself on the edge of the Espanyol box with a neat touch from Xavi's pass.
Then, in the blink of an eye, he curls the ball around an away defender into the tightest place possible - the bottom right corner of Kiko Casilla's net. Stunning stuff.Copyright: AFP
Oh my word. It could, should, have been a second Espanyol goal. Barcelona are all over the place at the back as away midfielder Victor Sanchez strolls in behind Dani Alves. His first touch is a little heavy though, allowing home keeper Claudio Bravo to rush out of his goalmouth to boot clear. Big let off.
Five minutes for Barcelona to go into the break level. Even if they nab an equaliser then I'm sure it won't stop Luis Enrique dishing out the hairdryer treatment.Copyright: Getty Images
It's not quite the Battle of Alamo yet, but momentum is building for the home side. Left-back Jordi Alba ghosts in at the far post, forcing Espanyol keeper Kiko Casillas into a smart stop.
And right on cue, here is Luis Suarez. But the Uruguayan cannot put some dirt on Kiko Casilla's gloves, firing wide of the target.Copyright: Getty Images
leeban: Suarez on the wing is ridiculous he can really do damage playing centrally
Barcelona need some Messi magic. He drops the right shoulder, steps on the gas, jinks past a Espanyol defender, but is crowded out by a stretching Eric Bailly as he is about to pull the trigger. Top defending.
Another Barca chance - but this one is more comfortable for Kiko Casilla. Barca defender Gerard Pique jumps highest to meet Ivan Rakitic's right-wing corner, only to head straight at the Espanyol stopper.
Almost! Lionel Messi stands menacingly over a 20-yard free-kick which the Barca talisman caresses over the nervous-looking Espanyol wall. Visiting keeper Kiko Casilla is stranded...but the crossbar comes to his rescue. It is still shaking now.Copyright: AFP
Now it's Espanyol who look likeliest to score the second of the evening. Away goalscorer Sergio Garcia is stood in acres of space at the far post, but his shot lacks power and is easily gathered by Barca keeper Claudio Bravo. Turning point?
Lionel Messi - have we mentioned him yet? I don't think so. That's because we have hardly seen him. Now the Argentine pops up, pulling the strings from deep, before Espanyol hack away another poor Barcelona cross.
This is like Groundhog Day at the moment.
Barcelona have possession. Barcelona misplace a pass. Espanyol boot clear. Barcelona start again. Repeat.
Jordi Alba's fizzing cross from the left is Barcelona's latest opening. But there is not a red and blue striped shirt in the six-yard box to nudge in the equaliser.
Spanish football writer Andy West: You can't draw any meaningful conclusions from 15 minutes of football but this has been a spectacularly abysmal 15 minutes from Barca.
DeathApeDisco: Barca at the point with Xavi Man Utd reached with Keane, Liverpool with Gerrard. Great player, but shouldn't play this much.
Here's an opening as Barca finally show some urgency. Sergio Busquets pops up on the right side of the Espanyol area and pulls back to Xavi on the edge. But the Barca captain miscues his first-time shot and skies over the crossbar. Cue the sound of jeers ringing in his ears.
All pretty predictable from Barcelona though. The home side pass, pass and pass. Switching the ball from side to side as they aim to pick a hole in the Espanyol defence. But the visitors have 10 men behind the ball, sometimes 11, at every opportunity. No way through yet.
Sergio Busquets looks distraught. Not the start he envisaged to his 300th appearance as he slept last night.
Back come Barca, hogging possession and territory since the restart. The words 'red rag' and 'bull 'spring to mind.Copyright: AFP
Well, well, well. The Nou Camp falls silent. Espanyol score against Barcelona - for the first time since January 2012!
And it was dreadful defending from Barcelona. Sergio Busquets - in his 300th Barca appearance - is easily dispossessed on the left touchline leaving Espanyol bearing down on the home goal in a 2v2 attack. But Sergio Garcia (not the golfer) goes all alone and rolls into the bottom left corner.Copyright: AFP
"Penalty!" scream the home fans. Not a chance. Veteran Barca star Xavi bursts (yes, bursts) into the penalty area, but goes tumbling over the body of Espanyol defender Alvaro Gonzalez. However, he simply innocuously slipped on the Nou Camp turf. No foul. No penalty.Copyright: AFP
Hang on! This wasn't in the script - Espanyol almost bag the opener. Barca are scrambling as a low cross comes in from the left, but the home defence manage to clear before Felipe Caicedo (remember him Manchester City fans?) sticks an outstretched foot there first.
In keeping with this somewhat mis-matched Spanish derby, earlier we asked which other team you feel have spent more time in the shadow of their local rival than any other...
John McEnerney: Poor old Torino in the shadow of The Old Lady with all that Fiat money they never stood a chance & never will!

Still no respite for the away team. Ivan Rakitic swings in a delicious ball from the right corner of the penalty box, towards the far post where Luis Suarez is lurking with intent. But Espanyol defender Alvaro Gonzalez is well-placed to head clearCopyright: AFP
Barcelona playmaker Xavi, making his 30th derby appearance, sticks on the passing radar to slice open the Espanyol defence with a 30-yard pass through the middle. It finds the feet of Luis Suarez, like a sat-nav reliant car finding its well-hidden destination, but the Uruguayan is crowded out by a couple of blue and white shirts.
Here's what is going to happen for much of the next 90 minutes or so. Barcelona have the ball and attack. Espanyol don't have the ball and defend for their lives.
That pattern begins inside the opening two minutes, only for the hosts to hand back possession when Luis Suarez strays offside on the left flank as he is picked out by Neymar.Copyright: AFP
Luis Suarez taps the ball to partner-in-crime Lionel Messi - and that means the 161st derby is under way. Game on!
If Barcelona nab the three points that many expect them to, then Luis Enrique's men will move within two points of La Liga leaders Real Madrid.
In case you didn't already know, Cristiano Ronaldo stole the show AGAIN as player and club smashed more records on another historic night at the Bernabeu.
I'm sure they'll be a record out there that Lionel Messi can rack up today...
What could you do in 455 minutes? Watch the entire Godfather trilogy. Fly to New York City from the UK. Or not concede a goal against your local neighbours.
Espanyol have not scored in their last five league meetings with Barcelona - but they have never before gone six games without a goal.
It has been 455 minutes since Alvaro Vazquez scored the last derby goal for Espanyol on 8 January, 2012.
Inspired by Espanyol's position as long-suffering neighbours to Barcelona, we want to know which other team you feel have spent more time in the shadows than any other. And, equally importantly, why?
Manchester City could certainly have laid claim to that unenviable crown before their recent resurgence on the back of Shiekh Mansour's millions. How about Roman side Lazio? Or 1860 Munich?

Buenos dias amigos! And welcome to our live coverage of Barcelona v Espanyol - or the 'Derbi Barcelona' as it is otherwise known.
Barcelona are 22-time Spanish champions and four-time European kings. Oh, and throw in two world titles and shed loads more silverware. Espanyol have four Copa Del Reys to their credit...and not much else.
Spain's second largest city - the capital of Catalonia - is buzzing with excitement. Or should I say the bars populated with home fans will be buzzing.
A sense of trepidation might be lingering in the air of Espanyol-coloured bars. And here's why....

The chances of many Espanyol supporters being au fait with UK comedy Harry Enfield and Chums are probably slim to none.
But any who have happened to stumble across the classic 1990s sketch show might feel sympathy with the downtrodden couple who are constantly told by their posh Brummie neighbours that "we're considerably richer than yowww".
Stan and Pam Herbert boast about their expensive motors, flashy clothes and glitzy jewellery. Espanyol's neighbours Barcelona boast about a bursting trophy cabinet, lucrative sponsorships deals and signing the world's greatest players.
"Estem considerablement mes ric que tu" (the Catalan translation of the Herberts' famous catchphrase) may or may not be heard at the Nou Camp today...
