- Real move four points behind Barca
- Ronaldo scores a hat-trick
- Milan earn comfortable win over Inter
Earlier today Gary Neville's Valencia were booed by their own supporters after Antonio Sanabria's penalty eased Sporting Gijon's relegation worries.
Neville is still waiting for a first league win since taking charge of Valencia in December.
Former Barcelona B striker Sanabria, on loan from Roma, scored his fourth goal in two games after Danilo tripped Jony.
Alvaro Negredo missed three chances to equalise, heading one against the post, then chipping wide and blazing over.
AC Milan remain eighth in the Serie A table but they are now five points behind fourth-placed Inter. Next up for Milan is an away trip to 14th-placed Palermo on Wednesday while Inter host 12th-placed Chievo on the same night.
The last time Milan scored more than two goals against Inter was in 2011. The party is under way for the fans wearing red and black scarves.
The Rossoneri have a victory to savour.
Inter were thumped by Juventus in midweek in the Coppa Italia and they've on the brink of a big defeat by their fierce rivals. It's been a terrible few days for Roberto Mancini.
Three minutes of additional time. Milan are just trying to keep possession and eat up another few seconds. Their work is almost done.
Three minutes of normal time remaining. Inter can have few complaints about this result. They will point to Mauro Icardi's missed penalty as the turning point but you can bet the inquests are already under way.
Red and black scarves are out in force. Milan are on their way to a memorable victory over their fierce rivals. Nights like this have been short in supply for the Rossoneri.
So close to a fourth....Carlos Bacca gets in front of substitute Mario Balotelli and flicks an effort narrowly wide. This is turning into an embarrassing night for Roberto Mancini and Inter. Around seven minutes of normal time remaining.
Inter have pressed the self destruct button and Milan have almost certainly sealed victory in the space of a dramatic few minutes after M'Baye Niang sweeps home his side's third goal.
Milan have not had much to celebrate lately but this is turning out to be a memorable night for the Rossoneri and their fans.
A dramatic few minutes as Inter miss a great chance to equalise and Milan go up the other end and extend their lead. M'Baye Niang delivers a super cross for Carlos Bacca to extend his side's lead after getting in front of Miranda.
AC Milan fans celebrate wildly as Mauro Icardi hammers his spot kick against the post. How costly will that be?
Lifeline for Inter as the referee points to the spot after goalscorer Alex fouls Mauro Icardi.
Espanyol's night goes from bad to worse. Jese has been excellent since he came on providing the team with fresh energy. He drives at the visitors defence before crossing and Oscar Duarte can only divert the ball past his own keeper while trying to clear.
Never write Cristiano Ronaldo off! The Portugal forward has another hat-trick to add to his collection after meeting Jese's cross inside the six yard area. Espanyol's marking has been atrocious but Real's fans are loving this.
It was never going to be a thriller in Milan. Two mediocre teams who have fallen on hard times. There's plenty of effort on show but what was once one of Europe's most anticipated derby games is short of quality.
Karim Benzema's work is done. He's given a rest ahead of the midweek game away to Granada and on comes Lucas Vazquez. Cristiano Ronaldo is running out of time to get another hat-trick.
Another Real change. Midfielder Casemiro is on for Toni Kroos. Around another 15 minutes to go in Spain.
It's all kicking off in Milan. Sixteen-year-old Milan keeper Gianluigi Donnarumma makes a hash of a clearance before clattering into Eder. Inter want a penalty but the referee awards a goal kick which provokes Roberto Mancini into a touchline rant.
Cristiano Ronaldo has well and truly answered his critics with a sumptious performance. He's on a hat-trick and when the hosts win a free-kick 20 yards from the Espanyol net he grabs the ball. Up steps Real's No 7...and it lands on the roof of the net.
Inter's players were back out on the pitch a good three minutes before the opposition re-appeared. No doubt Roberto Mancini has told a few home truths. A big 45 minutes coming up for Inter. Back under way in Italy.
Midfielder Luka Modric gets a standing ovation from the Bernabeu faithful - as well as a handshake from Zinedine Zidane - as he is replaced by young forward Jese. Around 25 minutes of normal time remaining.
That's more like it. More tricks from the boot of Cristiano Ronaldo who pings in an inch-perfect cross for Karim Benzema but the French striker heads straight at the keeper from six yards.
Change coming up Real. It's needed. They have been pretty pedestrian this half.
Espanyol actually stopped Barcelona from scoring in a league game as recently as 2 January. They're making a better fist of this than they managed before half time. Real have come out in second gear.
There's still a long way to go but it's fair to say the points are heading Real's way. What will that do at the top of La Liga? Well, Real will remain third but only one point behind Atletico and four adrift of leaders Barcelona, who have one game in hand.
No sign of a fifth goal in the first five minutes of the second half at the Bernabeu. Indeed, Espanyol have been more threatening in the opening exchanges of the new half than they manged throughout the previous 45 minutes. That said, they still don't like scoring though.
BBC Sport's Henry Ditchfield in Milan: "Defeaning noise as Alex scores for Milan. The man on the stadium microphone is repeatedly announcing Alex's name with the fans singing it back. A flare has just gone off, red mist descends."
Back under way at the Bernabeu where it is already a damage limitation exercise for hapless Espanyol.
Five minutes of the first half left in Milan. Inter's season is threatening to unravel. Having been hammered by Juventus in the Coppa Italia in midweek they are now losing to their fierce rivals. Roberto Mancini does not look happy.
The Milan derby explodes into life through an unlikely source as Brazilian defender Alex rises above two Inter defenders to meet Keisuke Honda's cross and head past Samir Handanovic from seven yards out.
A view from the press box in Milan. There's not been too much to get the fans excited about in the opening half an hour. Inter started well but Milan are showing signs of getting on top with midfielder Juraj Kucka causing problems.
