Join us to find out. See you there.
Bayern captain Philipp Lahm: "The fans have been really great today. We believed in the miracle, but we couldn't make it happen.
"It's impossible to stop those players for the whole 90 minutes. We didn't lose it today, but in the first leg."
It's a cliche when managers say 'every game is a final' but in Barca's case that is true now.
They can win La Liga this weekend against Atletico Madrid, face Athletic Bilbao in the Copa del Rey final and have the Champions League final on 6 June.
Enrique: "We're one win away from winning each of the three competitions. This is our mission."
Barcelona midfielder Andres Iniesta: "Bayern improved in the second half, but you have to celebrate the fact we've reached the final. We are where we wanted to be but won't just be happy with that, we want to win titles. We are in a final and it is within our reach. We will try and win it."
Barcelona midfielder Ivan Rakitic: "It was a really hard game for us and we were playing against one of the best teams in the world. The first game's result made it easier but in today's big game, we are now we are really happy and want to win it.
"Our coach is very important for us. Every coach has different ideas and I want to thank him from our team. Without him, it is impossible. It was perfect work from everybody and I hope we can win this title now.
"We respect all the teams and tomorrow is a big game for Real Madrid and Juventus."
Less possession, less time spent in the attacking third - but it's Barcelona making the trip to Berlin for the final next month.
Stepan Benyovszky: Enrique deserves so much more praise than he gets. It's him who sets his team up so that they get the most from the front three.
Hard to assess Barcelona's showing in that second half as the tie was realistically well won. But they didn't have a a shot on goal in the whole 45 minutes and allowed themselves to come under heavy pressure. They were noticeably weakened by the half-time withdrawal of Luis Suarez.
El Clasico final? The hype machine will be into overdrive if Real Madrid beat Juventus tomorrow night.
Juve have been excellent all season though and lead 2-1 after the first leg.
Allan Abbas: The form Barca's front 3 are in don't see them losing this one. They are going to win the treble. Just 3 matches away from it.
mariusz langner: The unselfishness from Neymar & Suarez is astonishing!! Really great attacking team work
Sammiexxx: It is all over! Thoroughly enjoyed the game. The better team won at the end of the day. Barca well done you deserve it.
Chris Rod: I still blame #Guardiola no reason why Bayern should be down against this Barcelona side. They're a more complete team.
Henry Ice: Interesting that Luis Suarez has gone a whole season without any negative incident at #Barca. #MessiNeymarSuarez effect.
Barcelona are into their eighth European Cup final, they have won four of the previous seven. Will they equal Liverpool's total of five in Berlin?
Another reminder about that Champions League final date as it's later than normal. Saturday 6 June, in Berlin.
Barcelona will face either Juventus or Real Madrid. Should be brilliant either way!
Anyone going? I'm on a stag do. In Huddersfield. Great...
Barcelona into the Champions League final! A long and heartfelt embrace between Luis Enrique and Pep Guardiola on the sidelines, the better team won but it was an excellent tie over the two legs.
Whoever beats Barca will certainly deserve the trophy. This is a fantastic team.
Neymar in for a hat-trick! Oh what a touch to get past the last man, just genius stuff, but he gets his lines wrong at the crucial moment, he squares for a Lionel Messi tap-in but over cooks it and pushes the number 10 wide of goal. A real chance for a treble...
THREE MINUTES added on. Robert Lewandowski almost finds Mario Gotze running in behind but Dani Alves sweeps up superbly.
'Hey! Hey! Super Bayern, Super Bayern!' is the chant as the fans continue to pogo in the stands. The hosts have made a go of it but those two away goals really put this tie to bed inside half an hour.
How's your strength in depth? Bayern bring on World Cup hero Mario Gotze and the most expensive signing in Bundesliga history, Javier Martinez, for the last few minutes. Off go Thomas Muller and Bastian Schweinsteiger.
Robert Lewandowski pulls the ball down on his chest and curls one wide from 20 yards. You can't fault Bayern for effort tonight - just fault their shoddy defending. They've had 19 shots, Barca just five.
Cephas Ifeanyi: Barca just used their hand brake.
FEMI JOHN ATOYEBI: Boring boring #Barcelona. 10 men behind the ball.
Tom Strafford: Barca are looking lazy and Messi just had a poor touch. This might get interesting.
Thiago, to Robert Lewandowski, one more! Yes, on to Thomas Muller - he could go for a powerful drive or a cutback and in the end he does neither reallly, screwing a half-cut ball across the face of goal. Shame, the move deserved more.
Barcelona just soaking up pressure now which is not really their style. Another Bayern goal could make life interesting. They need three in the last 10 minutes.
Neymar rather unnecessarily volleys a ball into the stands and very close to Pep Guardiola's head. Lionel Messi gives the ball away and Robert Lewandowski sees his shot deflected wide! The crowd believe this you know. They are used to seeing the improbable happen...
Chris Goodall: Barcelona inviting unnecessary pressure on themselves, they've stopped playing since half time. Very risky.
Rijesh: Game just got interesting.
Kanayo Umeogu: Now just 3 more goals for Bayern to score.
Xavi on for Andres Iniesta, Xavi making his 150th Champions League appearance. Barca may be in for a more tense last 15 minutes than they thought - but they should still be home easily enough.
Thomas Muller with the enthusiasm of a springer spaniel. He strokes home a fine strike from the edge of the area and retrieves the ball, before whipping up the crowd and calling for more support. He still believes!
Bayern need three more.
Last 20 minutes then. The game has gone nowhere in the second half but Barca put the tie to bed long ago. They bring on Jeremy Mathieu for Ivan Rakitic - Javier Mascherano in midfield?
Philipp Lahm trots off and Sebastian Rode comes on into the Bayern midfield. A thankless task tonight really.
Barca's transmission hits a false neutral as first Javier Mascherano and then Neymar needlessly give the ball away under no real pressure. Unforced errors. Double faults. Thoughts on Berlin, thoughts on going on strike perhaps.
Barcelona midfielder Ivan Rakitic goes in the book for a late challenge on halfway. It's been an easy night for English ref Mark Clattenburg and his fellow officials.
Robert Lewandowski must be high on the 'best free transfers' list. Excellent penalty-area play. Bayern whip in a free-kick and Thomas Muller swivels to plant a shot wide.
Well that is top class. Simple as that. Robert Lewandowski gets the ball to feet, just inside the area, he squares up Javier Mascherano, rolls the ball from left foot to right and then in one movement sweeps a curler into the far corner. Lovely stuff.
Bayern need four more.
So it looks like a summer of reflection for Bayern Munich. A good, but not great season. They've not had much to do to win the Bundesliga and they've badly missed Arjen Robben and Franck Ribery. Ironically they could have done with Xherdan Shaqiri this year...
Xavi gets a sprinkling of applause as he warms up down by the corner flag. The intensity and tempo has gone from this game now. Barca are through and we all know it. No injuries or suspensions is the order of the day now.
Neymar sent tumbling by Jerome Boateng, who is at least close enough to foul them tonight. Pedro has been quiet since coming on.
Bastian Schweinsteiger picks the ball up in a good area but his touch just lets him down. Barca keeper Marc-Andre ter Stegen pings a sweeping 60-yard ball over the top but Bayern counterpart Manuel Neuer meets it 30 yards from goal with a flying header. Two wonderfully good footballing keepers.
Bayern fans still making noise, I think they're singing a chant to the tune of 'Don't you want me' by the Human League. Bet Phil Oakey never saw that one coming...
Thomas Muller has come out pumped up, throwing his weight around and then arguing with the linesman. Barca happy to just take their time now, Gerard Pique and Javier Mascherano dictating from the back.
Luis Suarez is off at the break, on comes Pedro. Will he be the Barca forward to leave the club this summer? There's always one.
Neymar is enjoying himself...
Here they come, Bayern Munich defender Dante has a hug with Brazilian compatriot Neymar in the tunnel. Dante probably glad he's not playing...
John McEnerney: We'll see Pep in the PL sooner than he himself thinks, doubt the Bayern legends sitting in the stands will take much more of this.
Sprightly CHAMPIONS: Make a case in defence of Guardiola, but Bayern have always been the top team in the Bundesliga. He did the bare minimum there.
O'mon Ilaboya: Regardless of modern focus as well as ingenuity and pace of modern attackers,I still believe quality of defenders has dropped.
What will Bayern's approach be now? Settle for a defeat or go for it and lose by more on aggregate?
Bayern Munich had seven men back against the Barca front three for Neymar's first goal. It wasn't enough.
Roy Keane is in usual hard-hitting form on ITV.
"It's been like kids playing on the street. First to 10 stuff. But this is shocking defending, if an under-18 did that you'd be tearing your heat out! Basic defending."
Are Manchester United fans more knowledgeable about football than Liverpool fans?
According to our BBC Sport Predictor league they are, with Man Utd in 51st place and Liverpool in 87th after the opening round of our new Premier League game.

Bayern boss Pep Guardiola is talking to Lionel Messi as the sides go off the pitch - he gives Messi a pat on the head. 'Give it a rest son.'
Short memories some of you lot! Barcelona under Pep were pretty decent as I recall. Just ask Sir Alex Ferguson.
Will we see Guardiola in the Premier League soon enough though?
Nick from Burnley: The people saying Barca are boring were in the Pep days with the high possession and overloading the flanks. This Barca team is just pure magic where you don't know what's coming next except a goal.
James in London: Whether they're better is debatable, but this Barca team are far more entertaining to watch than in the Guardiola era
A Spanish court could decide on Wednesday if the strike affecting the end of La Liga season is legal.
The Spanish Football Federation (RFEF) has suspended the end of the season and the players' union (AFE) also decided to strike in a row over TV rights.
The proposed action puts the final two rounds of league games in doubt, as well as the Copa del Rey final.
Barcelona, who play Athletic Bilbao in the cup final, are only one game away from wrapping up the league title.
They would become champions by beating current holders Atletico Madrid on Sunday, if the game is played.
BBC World Service Sport
"If the Spanish strike/suspension goes ahead the second half could be Barcelona's last 45 minutes of football until 6th June - the Champions League final."
Brilliant from Barca, brutal on Bayern.
Medhi Benatia flashes another header wide as Bayern threaten from a set-piece. Time to start to think about the final in Berlin on Saturday 6 June - both Real Madrid and Juventus will fancy their chances of scoring against this Barca side from a set play.
How they stop that front three tearing them to shreds is another question...
You have to say the Barcelona attack are just outstanding. Neymar and Luis Suarez play an outrageous one-two which takes four or five defenders out of the game in a flash but this time Neymar's pullback is disappointing. The only real surprise is that he didn't smash it on the volley, Van-Basten style.
Matt Barron: Lewandowski could have had a hat-trick by now. Poor finishing
Frank k Mponda: Attack is the best way to defend. These are 2 teams giving us an end to end stuff. One's clinical than the other
Myikal: How many chances do Bayern want? This should be at least 4-2 with the clear chances wasted
The last Champions League team to have two players with eight or more goals in a campaign was Manchester United in 01-02 (Van Nistelrooy 10, Solskjaer 8). Messi has 10, Neymar 9.
GOT TO SCORE!
Not sure if this is a brilliant save or a terrible miss, but either way Bayern Munich should be level on the night. Brilliant again from Thiago who carves himself a channel through the middle before coughing it up to Robert Lewandowski in the area. The Pole turns and batters in a shot which Marc-Andre ter Stegen gets a big hand on to.
The ball is drifting into the net but ter Stegen does superbly well to get back and scoop it out from right on the line. Excellent recovery!
Excellent header from one of Bayern's old generals, Bastian Schweinsteiger with the late run into the box and a powerful header which requires a strong wrist from Marc-Andre ter Stegen to turn over the top.
Allan McDevitt: There is absolutely zero logic in setting up a defence like that vs Barcelona. Pep has destroyed that 2013-winning side
Will Jackson: Pep may know how to set up to attack, but he is clueless on how to set up when defending. Beckenbauer to be defensive coach?
Elliot Riddle: Bayern Munich need to do a Swindon Town to come back from this!
Brilliant from Luis Suarez, lifting the ball over his and a defender's head with some sort of amateur gymnastics, tremendous. Showtime in the Allianz. Bayern not shutting up shop yet, we could have a hatful more at either end at this rate.
Three touches for Neymar inside Bayern Munich's penalty area and two goals. Clinical stuff.
Matt Palmer: Bayern just handed that to Neymar on a plate
Jamie Millar: Guardiola being found out. Playing 3 at the back against the front 3 of Barca!? Suicidal tactics.
Jas Grewal: Well you can group Bayern into the poor naive defending teams in Europe along with the English clubs.
All credit to Bayern fans, they're still jumping up and down and making a right old go of it. Amazing what a diet of good beer, sausages, cheap tickets, a dominant team on the domestic front, Pep Guardiola in the dugout and a cracking city to live in can do for morale.
Pep Guardiola is out on the sidelines but I'm not sure what he can say.
'Come on lads, we only need five more!'
It's another goal right out of the console game textbook! Bayern Munich again go missing on the break, it's two-on-two and Luis Suarez is very unselfish, picking out Neymar at the back post, the Brazilian having time to chest it down and then lash home into the near corner. Emphatic.
They lead Bayern Munich - dominant in Germany - five one on aggregate, with two away goals. Are people still saying Barcelona are boring?
When did Lionel Messi get a big sleeve of tattoos? Not the most pressing issue of the night, but still. Messi has his first shot of the night after more good interplay between himself and Luis Suarez, but he can only stab a shot at Manuel Neuer.
At the other end former Barca man Thiago weaves through brilliantly but Thomas Muller's effort is tame.
Robert Lewandowski rifles in a toe-poke after more good work from Thomas Muller but it's right at Marc-Andre ter Stegen in the Barca goal.
Barcelona may have spent most of the opening stages in their own half, as shown by their heat map above, but they only need a few seconds to have an effect further forward as shown by Neymar's equaliser.
It's only a year since many of us were doubting Neymar's place in this Barca team. But he had a brilliant World Cup on home soil and has now scored more than 30 goals for Barca this season.
Neymar, Luis Suarez and Lionel Messi have scored 113 goals between the three of them. The latest has acted like a tranquiliser on the Allianz Arena.
That goal has put a dampener on the atmosphere, but the Bayern fans are still roaring their team on. If you can't enjoy watching your team, you can at least marvel at Barca's front three. But Bayern won't lie down, Thomas Muller meeting Philipp Lahm's cross with a flicked header that forces Marc-Andre ter Stegen into a decent save.
Paul gibbons: That's what you get for playing 3 against 3 at the back, Pep a genius? Give me a break.
Madan Roka: The front 3 in perfect harmony. If Messi touches, then there is something coming.
Mufc Believer: Game over, really. Bayern now need to score 5.
It was a gamble [11 mins] that backfired for Bayern Munich. That away goal for Barcelona now means that Bayern need to score five on the night.
A big, big ask...
Play with fire, and you'll get burnt. Bayern Munich's soft underbelly is ruthlessly exposed again as Lionel Messi slides a ball between the gaps in their defence, Luis Suarez in onside and squares it for Neymar as Manuel Neuer comes out. A tap-in you've all scored on Fifa many, many times...
Bayern Munich are making this such a great game to watch! They leave it light at the back again, Luis Suarez is one-on-one with Xabi Alonso but picks a poor pass, and then Bayern flood upfield. Thomas Muller and Robert Lewandowski almost cut Barca right down the middle but the men in yellow recover well.
Bayern going all out to gamble here and get another one.
Momentum is a funny thing in sport. Barcelona still hold all of the cards but that early Bayern goal can't help but give them belief. The atmosphere is tangible.
Shohidur Rahman: Bayern needed an early goal and they've got one. 83 mins to get 2 goals. Game on.
Alex Haworth: Bayern are going to win this match 4-0 tonight.
Kenneth Gyang: Astonishing support from Bayern fans. Inspiring.
Never write off the Germans. Never.
Bayern Munich have scored four goals or more in a game on 14 occasions this season but a 15th tonight would be truly sensational. Can they keep a clean sheet though?
It's just like watching Swindon!
Barcelona defend like Sheffield United, leaving Medhi Benatia completely free just eight yards out and he powers in a header which Marc-Andre ter Stegen can only get a hand to and push into the corner.
Exactly the start the tie needed. What a noise in Munich!
Yes, yes, yes! Brilliant start to the game. Moments after Ivan Rakitic's chance for Barca, Bayern counter with real intent. Philipp Lahm sends Thomas Muller away down the left, Bayern have men over, Muller waits before picking out Thiago arriving at full tilt, his shot looks on target but Gerard Pique makes a block.
It's all very well saying that Bayern need an early goal but they need an early touch of the ball first. Barca keeping it.
And now a chance! Dani Alves' ball through for Ivan Rakitic, ghosting in behind like a young Bryan Robson, but his low shot is well saved by Manuel Neuer.
Bayern haven't scored a goal in six hours of football; Barcelona have scored 19 goals in that time. Extraordinary!
Barca, in fluorescent, 90s rave yellow, make a start befitting a team pumped full of confidence. They keep the ball for fun, Lionel Messi trying an outrageous pass over the top with the outside of his foot. High tempo, terrific noise.
Here we go! Mark Clattenburg gets us under way.
A brilliant mural of the European Cup is displayed by the home fans who are making plenty of noise in Bavaria. An early goal for their boys and we may see what Barca are made of.
They spell out 'One city, one dream' on the far side of the stadium too. I had to put that through a translation tool as I can't speak German. I don't get sent to see Jurgen Klopp though...
Bayern Munich: Neuer, Rafinha, Benatia, Boateng, Bernat, Lahm, Schweinsteiger, Alonso, Thiago, Muller, Lewandowski. Subs: Reina, Dante, Javi Martinez, Pizarro, Gotze, Rode, Weiser.
Barcelona: ter Stegen, Dani Alves, Pique, Mascherano, Jordi Alba, Rakitic, Busquets, Iniesta, Messi, Suarez, Neymar. Subs: Bravo, Xavi, Pedro, Rafinha, Bartra, Adriano, Mathieu.
Referee: Mark Clattenburg (England)
Lionel Messi and Cristiano Ronaldo could become the first players to be involved in 100 goals in the Champions League.
Here we go then, the teams are set to emerge from the tunnel at the impressive Allianz Arena. Mission impossible or a night of legendary comebacks?
Will it be as good as Swindon v Sheffield United? We wish...
Lionel Messi has scored 77 Champions League goals, four more than the starting 11 of Bayern Munich.
It seems everyone loved a bit of Ronaldinho in his pomp. What a player. Reducing the Bernabeu to silence, curling around John Terry, that ridiculous shuffle from left to right foot.
Blackburn might get him this summer.
SETH: Barca's team with Eto'o, Giuly, Ronaldinho and Deco winning the UCL is just the Best ever!
Steven Chandler: The current side. The front three make most defenders quake in their boots, and they have a cutting edge like a razor blade.
CHAMPIONS: 2006 (winners) Ronaldinho Eto'o Deco. Guile. Technique. Pace. Craft.
Staying positive? This Bayern fan looks happy enough. A 4-0 win and you're through...
Lionel Messi has 10 in this season's Champions League - the top scorer again. One more tonight - and an away goal - and surely this tie is toast.
Bayern need an early goal to keep it interesting.
Sam: Not sure how anyone can argue against the 2011 Barca team. They completely dominated Man United in the final and Sir Alex said himself they were the best team ever.
Cristiano Ronaldo has also scored an amazing nine goals in Champions League semi-finals.
A combined XI would walk the floor with anyone, surely?
Lifa Nati: No contest really, the Ronaldinho era was a marvel to watch, but Messi just perfected the art with the # of goals scored.
Robert Gleed: 2011 are the best team I have seen. Could be argued 2006 and 2015 were/are more entertaining, but 2011 were just unplayable!
Shaun: Can we have a combined XI? Ronaldinho in for Neymar, Koeman and Puyol in defence. Xavi in his prime for Rakitic

FC Barcelona on Twitter: The players in the visiting team's dugout at the Bayern Arena
Relaxed enough lads?
RougeMen:EF: 2011 for me. Maybe didn't have the superstar forward line as 06 but they humiliated Man Utd at Wembley. One of the best teams ever.
Robert Chui: Barca 2006 Eto'o, Ronaldinho, Xavi, Inesta and Deco in their prime.
How do you stop this man? If anyone knows, give Jerome Boateng a quick call.
Not much love for David Villa there! A class act. Brilliant goal at Wembley in 2011.
Samar F Keirouz: Oh come on!! NO-ONE Compares to Ronaldinho!! EVER! I love David Villa but there is no comparison.
harrywilde: How are you even comparing Villa and Ronaldinho? #RonnyDinadifferentclass
Champions League on Twitter: Bayern have a 100% record in Munich in this season's #UCL, and have scored 13 goals in their last two home games.
Not bad numbers from Messi in last week's first leg...
Bayern boss Pep Guardiola: "The only way we can make the final is by playing better than Barcelona and doing what we did in the second half [of the first leg].
"Our only desire is try until the end."
Bayern Munich have won their last five home games in the Champions League, averaging 3.8 goals per game and keeping a clean sheet four times in this run.
Simon Chilcott: The 92 one. I was there in 94 when they beat us 4-0 and Hristo scored a measly hat-trick.
Laurence Chaffey: Ronaldinho, Eto'o and Deco all in their prime... pretty amazing. Hard to chose between those 3 and Messi, Neymar and Suarez
Devine Ncube: 2006 was the best. Ronaldinho, Eto'o and Deco was so interesting especially Ronaldinho.
Barcelona come into the game in sensational form and look confident that they can win the treble.
Luis Enrique was able to make five changes - including benching Andres Iniesta, Jordi Alba and Sergio Busquets - but his side still managed to beat David Moyes's Real Sociedad 2-0, to move to within one victory of the title.
In fact (presuming the suspension on the league is lifted) they can win the title next weekend at Atletico Madrid, the current champions.
No surprises on the teamsheet at the Allianz Arena - both managers name unchanged sides from last week's first leg in Spain.
That means Bayern Munich recall the likes of goalkeeper Manuel Neuer, midfielder Xabi Alonso and defender Medhi Benatia, who were all rested for Saturday's 1-0 defeat against Augsburg.
Barcelona also shuffled their pack at the weekend, with midfield duo Andres Iniesta and Ivan Rakitic, plus left-back Jordi Alba, missing the 2-0 win against David Moyes' Real Sociedad.
The key trio return to Luis Enrique's starting XI, alongside young German Marc-Andre ter Stegen who continues as Barca's keeper in the Champions League.
Max Baggins-Craig: Barca 09, Xavi & Iniesta aren't congratulated enough for their efforts, Messi wouldn't be same without their input, simple as.
Themba mjajubana: 2015(winners?) Messi, Neymar, Suarez. This current trio is too dangerous.
Bayern boss Pep Guardiola probably needs the greatest performance of his managerial career to reach the Champions League final.
So the best way to warm-up is not to play 76 minutes with 10 men and bring on the key man you had intended to rest.
Despite having already won the German Bundesliga title, Guardiola decided to name the majority of his first-choice players against FC Augsburg at the weekend. However, keeper Manuel Neuer, midfielders Xabi Alonso and defenders Mehdi Benatia and Rafinha were left on the bench.
Within 14 minutes, Neuer had to come on anyway after Bayern keeper Pepe Reina, in his third appearance for the club, was sent off.
Four times Barcelona have won the European Cup, with four excellent sides.
But who were the best? If you had to pay money to see one squad, who would it be?
What would have made them even better?

Bayern Munich started last week's first leg in maverick style, playing three at the back against Barca's star-studded front three.
After a switcharound the game then tightened up until Lionel Messi unlocked the Bayern defence with a quick double and Neymar added a third in injury time.
Is it game over? You'd expect so. But don't tell Bayern that.
All the talk before last week's first leg at the Nou Camp was about the homecoming of Pep Guardiola.
By the end of the night, Pep was left to skulk away sheepishly, his Bayern Munich side left on the brink of elimination by a dazzling Barca showing.
And that man Lionel Messi was at the heart of it yet again...
Daily Telegraph Football Correspondent Henry Winter on Twitter: #fcbayern fans heading to Allianz
Barcelona are also unchanged from the first leg. No thoughts of shutting up shop then lads? One up front?
Barca XI: Ter Stegen; Alves, Pique, Mascherano, Alba; Busquets, Iniesta, Rakitic; Suarez, Messi, Neymar
Bayern Munich are unchanged from the first leg.
Bayern XI: Neuer, Alonso, Benatia, Thiago, Lewandowski, Rafinha, Boateng, Bernat, Lahm, Müller, Schweinsteiger
Bayern Munich are 3-0 down after the first leg. According to the boffins at Uefa HQ, Barcelona have 95.2% chance of going through.
Let's hope Pep Guardiola has a Han Solo-approach to dealing with the odds...
It's an age-old footballing maxim. Don't write off the Germans.
They never know when they're beaten. From the 1954 World Cup final to the 1970 quarters, the national team had made a habit out of it, while at club level Bayern Munich and Borussia Dortmund have produced stirring comebacks in recent years.
Remember Jurgen Klopp's reaction to his Dortmund side beating Malaga two years ago? 'Unbelievable.'
And Bayern were 3-1 down to Porto just last month before smashing six past them in the second leg.
But even the most optimistic Bayern fan must fear the worst tonight. Can they really put three past Barcelona? And concede none...?
