We will leave it there for this evening. Thanks for following, and keep an eye out for the full match report here on VAVEL UK shortly. Good night.
It was a strange game in the end, neither side at their best and both guilty of plenty of mistakes, most crucially Rafinha's for Ascensio's goal to make it 2-1. It was also the first game in the competition this season that Ronaldo hasn't found the back of the net, and by his own high standards he had a very quiet evening.
They will need to be better next week though. They made the most of Real's uncertainty at the back early on, but when they needed to respond they appeared to be lacking going forward, despite the efforts of the 35-year-old Ribéry.
Crucially, they have two away goals to take into Tuesday's second leg. Two goals seems a tough ask for Bayern at the Bernabéu, but of course everyone thought three would be too much for Juventus, and we all know how that nearly turned out.
So despite a slow start Real come away with an important victory in the semi-final first leg. In truth neither side can be all that happy with their performance this evening, but Zidane's men have the advantage.
Unfortunate scenes at the end, with a mini-pitch invasion. Probably no more than a dozen fans.
FULL TIME. BAYERN MUNICH 1-2 REAL MADRID.
90+4: Ribéry with a cross but Navas claims.
90+3: Bayern just don't have enough tonight now.
90+2: Ribéry and Rodríguez combine, with Rodríguez finding Hummels, but it breaks down. Benzema brings forward, has Ascensio to his right but goes to Ronaldo on his left, and he is offside.
90: Marcelo down in the Bayern half and the hosts take their chance, only for Ascensio, filling in at left-back, to clear. Four minutes added on.
89: Tolisso cross but Real clear as Lewandowski fails to make the most of it. As Real break, Thiago barges into Kovačić and gets a yellow card.
88: Bayern had to score there surely? Tolisso with a perfect ball to Lewandowski, but he somehow puts it wide. Not like him.
87: Ribéry wins Bayern a free-kick of the left. Rodríguez takes, headed clear by Varane, Rafinha puts it back in but Ramos then deals with that.
86: A Rafinha cross isn't adequately cleared, with Marcelo making a mess of it. No shot comes from it though.
83: Final change for Real, and it's not Bale. Casemiro makes way for Mateo Kovačić.
82: Real forward. Modrić to Ronaldo on the right, through Vázquez and back to Modrić, but nothing comes of the move.
81: Tolisso looks for Müller but the ball runs through to Navas.
79: Two balls end up on the pitch, but the one that matters finds its way to Ribéry once more. He goes up against Vázquez and wins a corner. Varane clears that.
78: Thiago puts it into the box, maybe a little over hit, Süle heads it back in but Ramos clears.
77: Casemiro brings down his one-time (and maybe future) teammate Rodríguez. He's booked, and Bayern have a free-kick in a good position.
76: Benzema with his first opportunity since coming on - he breaks clear but Ulreich is down to make the save with his feet. Martínez is holding an ice pack on his head on the bench, it seems that earlier clash of heads ended up doing for his night.
75: Final change for Bayern. Martínez is sacrificed for the return of Tolisso.
74: Thiago not happy as he's penalised for a challenge on Modrić. Free-kick to Bayern. Kroos takes it, but his international teammate Hummels clears it.
71: A long ball finds Real's leading man, but it brushes his arm as he tries to control it. He scores, but it's disallowed.
GOAL RONALDO! NO....
71: Vázquez in playing at right-back since Carvajal went off. And he's having to deal with Ribéry.
69: Ribéry is on fire at the moment. He has another shot but it takes a deflection for a corner. Real looking a mess at the back again. No danger from the corner, however.
67: Bayern close to scoring from the corner, and they want a penalty too. They get neither. Need to see a replay of that! Kimmich crosses in from the short corner, Martínez collides with Ramos going for the corner, but no penalty, and Müller tries to shoot but Lewandowski is in his way.
67: Caravjal down again meanwhile, and this time he is coming off. Benzema on - not at right-back, of course. A reshuffle is required.
66: Müller may have run the ball out of play but nothing given and he finds Rodríguez who wins a corner.
65: It looked like the change was coming, but Carvajal is allowed to take a throw-in. He may still be coming off though. All a bit strange at the moment.
63: An injury worry for Real now. Carvajal might have done his hamstring. Interestingly, it looks like Benzema is coming on.
62: A little lull in play as Lewandowski goes down. He's quickly back on his feet and Bayern look to press forward. Thiago with a ball into the box blocked, with Ribéry on the rebound denied again by Navas, who's had a good game, if you exclude the goal.
60: Ribéry allowed into the box again - this time it's a corner. Poor one from Kimmich though - over and past everyone.
59: Bayern begin their search for an equaliser. Ribéry goes it alone as he comes into the box from the left, however Navas saves once he gets his shot away.
57: Rafinha with an awful give away. Ascensio takes the loose ball, shares a one-two with Vásquez, who has time and space to beat Ulreich and put the visitors ahead.
GOAL MADRID!! ASCENSIO PUNISHES A BIG MISTAKE. 1-2!
56: Casemiro forward but Javi Martínez deals with him. Bayern then forward and win a corner, which is cleared by Varane.
55: Some slick passing from Bayern but Kimmich blocks off Ascensio out on Real's left.
54: Ribéry with another attempted cross, but it goes out this time.
52: Ribéry challenges for the ball with Varane. He gets the ball but leaves his studs in the defender. Kuipers only seems to see the latter, and gives the Frenchman the first yellow card of the game.
50: Bayern come forward for the first time - Ramos beats Müller to a header. Then another chance as Ribéry goes inside and tries to find Müller. Varane might get a touch though, and Ramos again clears. Concerns over der Raumdeuter's fitness may have been premature.
49: Keep an eye on Müller, he might be limping a bit early in this second half as well now.
47: A shot from Ronaldo, but it bends so much it goes for a throw in!
46: We're back underway.
We're about to get underway, but first a Real change - Isco makes way for Marco Asensio.
Real will have to improve in the second half if they are to build on that late equaliser. A key factor though could be that Bayern have had to use two of the substitutions already. Could they tire late on?
Despite losing both Robben and Boateng to injury. Bayern were the better side in that half, although Navas could have done better with Kimmich's goal. Nevertheless, Champions League winners in the last two years, Real have found a way to get back into the game.
HALF TIME. BAYERN MUNICH 1-1 REAL MADRID.
45+1: Rodríguez puts it in and Lewandowski heads it at Navas. He spills the initial save but claims the ball at the second attempt.
45+1: Vásquez concedes a free-kick after bringing down Ribéry very close to the box. He escapes a yellow but a chance for Bayern to go back ahead before the break.
44: Ramos floating ball put into the box by Carvajal. Ronaldo misses it but Marcelo on the edge of the box who fires in. They've been completely under the cosh yet the holders are level!
GOAL MARCELO! 1-1.
42: Bayern close again - Ribéry lays off to Rafinha on the left, with his cross finding Müller, who is left unmarked. His shot deflects off Ramos though. Hummels connects with the corner again but Navas claims it this time.
41: Bayern with a corner. Lewandowski gets a touch and Mats Hummels volleys over the bar.
38: Rafinha fouled. Carvajal getting a talking to from Kuipers, but no booking, which doesn't please the home fan
36: Boateng struggling to make his way from the arena. Someone who might be slightly pleased by this is future Bayern coach Niko Kovač - his Eintracht Frankfurt come to the Allianz Arena on Saturday, and with two injuries already, you can't see Heynckes making too many risks with his team selection.
35: Süle gets himself into the game by getting the better of Ronaldo in a duel.
34: Bayern forced into a second change already with Süle coming on. But they nearly score again! Thiago finds Ribéry but he makes a heavy touch in the box.
33: Looks like Niklas Süle will be coming on for Boateng. Another injury for Bayern! Navas meanwhile punches away a Ribéry cross.
31: Boateng tries to expose Real defensively again, Marcelo gets the ball off him and the Bayern defender goes down with a possible problem - perhaps his groin.
29: Possible penalty in favour of Lewandowski, he gets tangled up with Raphaël Varane but clearly nothing in that. Ronaldo is then given offside at the other end.
28: Rodríguez (who else?) starts it with a ball forward to Kimmich. He surprises Navas by going for goal, with the Real goalkeeper initially moving the wrong way. His late adjustment is not enough, and the hosts have the first goal of this tie.
GOAL BAYERN. JOSHUA KIMMICH MAKES IT 1-0.
27: Vásquez cross, Ronaldo gets a head to it but it goes out of play.
25: Kroos tries to find Ronaldo in the middle, but the ball takes a deflection and Real get another corner. Ramos gives away a foul as the corner is whipped in by the former Bayern man.
23: Isco unable to pick a pass in the box. Madrid trying to make something happen here. Eventually Carvajal runs in and fires towards goal. Ulreich is there though.
22: Long ball aimed at Ronaldo, however Sven Ulreich claims it.
20: Luka Modrić and Ronaldo combine on the right, but the latter's cross is blocked out by Boateng. Corner Real. Boateng heads that clear, as well. Kroos takes again, and Rafinha heads clear this time, with Bayern eventually winning a throw.
19: Rafinha with a shot on goal, but Keylor Navas is equal to it. All quite sedate so far, all be told. Then again, it was still 0-0 at this stage last night in Liverpool...
16: Rodríguez, from deep, finds Thiago, but Ribéry loses the ball. The visitors then want a free-kick when Ronaldo appears to be brought down by Jérôme Boateng, but the referee shows no interest.
13: A fair bit of possession for Real, but it's all in their own half. Eventually Vázquez concedes a free-kick for a foul on Rafinha.
10: Ramos tackles Lewandowski, with both players coming off worse for wear from that. Ramos, ironically, the one needing treatment.
8: All signs pointing towards Robben not coming back on - he's walking around the pitch presumably headed for the dressing room. And indeed Thiago is coming on. A big early blow for the hosts, but a class player to be able to bring off the bench.
7: Bayern playing with ten men whilst Robben is off. Real have possession and it's put forward towards Ronaldo but he's given offside - tight but a correct call.
5: A concern here for Bayern - Robben down on the floor getting treatment, looks like a leg problem of some sort. Thiago's warming up, but it looks like the Dutchman should be ok.
3: Isco and Ribéry already on the end of a couple of strong challenges. Bayern are able to get forward following a free-kick for the latter, with Robben crossing in. There's appeals for handball, but nothing doing for Kuipers. And it's the right decision - Ribéry struck it into the shoulder of Carvajal.
2: A Marcelo ball allows Kroos to break clear, but Real aren't able to create anything from the break.
1: 20 seconds in and we already have our first chance. Dani Carvajal allows Lewandowski to put in a cross but Müller can't make a connection.
1: AND WE'RE UNDERWAY.
Tonight's referee is Björn Kuipers from the Netherlands.
Müller and Ramos are wearing the armbands for the two sides tonight.
The players are out in Munich - it's almost time to get underway.
Five minutes to kick-off - will anyone repeat the heroics of Mohamed Salah and co last inght?
For more quotes from the two managers and more background on the game, don't forget to check out Brogan Clasper's preview before the match kicks off.
Meanwhile Heynckes admitted that stopping Ronaldo was a "big topic for us in the game analysis," however he also feels that Bayern have their own danger men, pointing to the 39 goals scored by Lewandowski in all competitions this season. He then posed the question (rhetorically) to Madrid - "how can you stop Lewandowski?"
One of the biggest sub-plots in this tie is Rodríguez going up against his parent club. Speaking yesterday, Real coach Zidane insisted that he "didn't want" him to leave on loan for Bayern. He thinks the Colombian will "do a good job," but "not to show me or prove me wrong."
Zidane has thrown a curve ball though, with no Karim Benzema or Bale in his starting line-up. Lucas Vázquez gets the nod, with Ronaldo set to lead the line.
No surprises in the Bayern team. Alaba doesn't make the 18, with Rafinha starting at left-back. It's fair to say Heynckes is going for it though, with all of Robben, Rodríguez, Müller and Ribéry starting behind Lewandowski. Thiago is on the bench, as is Tolisso.
Real Madrid: (4-3-3) Navas; Carvajal, Varane, Ramos, Marcelo; Modrić, Casemiro, Kroos; Vázquez, Ronaldo, Isco.
Bayern Munich: (4-1-4-1) Ulreich; Kimmich, Hummels, Boateng, Rafinha; Martínez; Robben, Rodríguez, Müller, Ribéry; Lewandowski.
Welcome back. With an hour to go before kick-off, the teams are in...
That is all for now. We will be back shortly with the team news and more build-up.
Real should have Nacho available again after injury, whilst Sergio Ramos will be available again after missing the second leg against Juventus through suspension. One player who may not start is Gareth Bale, who Zinedine Zidane has left out for much of the knockout stages, and when he did start, he was replaced at half-time against Juventus.
Aside from those absentees, Heynckes will likely play his strongest available side having rested several key men for the win against Hannover 96 at the weekend, although one of Thiago, Franck Ribéry, Thomas Müller, Rodríguez or Robben will have to miss out. Rafinha would fill in at left-back for Alaba, whilst Robert Lewandowski will lead the line, having scored six times in six previous matches against Real.
Bayern will be without Manuel Neuer, Arturo Vidal and Kingsley Coman, whilst David Alaba missed training on Tuesday as he recovers from a tight injury. Corentin Tolisso could make his comeback from a shin injury, although it seems unlikely he would start either way.
This match will see Toni Kroos return to his former club, whilst James Rodríguez is in the middle of a two-year loan spell from Real and Arjen Robben played for them as well between 2007 and 2009. Heynckes also has history with the Spaniards, leading them all the way in the Champions League in his only season in charge in 1997-98.
However, a double from former Bayern striker Mario Mandžukić plus a third from Blaise Matuidi looked to have earned Juventus extra time in the second leg, before the controversial penalty and sending off of Gianluigi Buffon. Cristiano Ronaldo kept up his second of scoring in every Champions League game this season to send them Real through from the spot.
In the Champions League they have mostly been their usual selves, despite finish second behind Tottenham Hotspur in their group. They swept past Paris Saint-Germain, Neymar and all, in the last-16, and looked set to beat Juventus with similar ease after winning the first leg in Italy 3-0.
Domestically, they have comfortably won the Bundesliga title for a sixth-successive season, whilst they are also into the final of the DFB-Pokal. Real, by contrast, have fallen well below expectations in La Liga, and with five games to go they sit in third place, 15 points behind likely champions Barcelona.
The hosts have had a superb season since Jupp Heynckes replaced Ancelotti in October. They have failed to win on only four occasions, including the goalless draw in the quarter-final second leg against Sevilla, having won the first leg away 2-1. That draw ended a record 12-match winning streak for him in the competition, extending back to the 2012-13 season.
Of course, they met in last season’s competition as well. In a reverse of 2012, the away sides won 2-1 in 90 minutes, but in extra time in the Spanish capital, Cristiano Ronaldo scored twice to complete a hat-trick has they sealed a 6-3 aggregate victory against a Bayern side now themselves managed by Ancelotti. They went on to win a third Champions League title in four years.
Real gained their revenge two years later though against the then-holders. They won the first leg at the Bernabéu 1-0, before putting the sword to Pep Guardiola’s Bayern, winning 4-0. Carlo Ancelotti’s Real then went on to beat Atlético Madrid to win La Decima.
The most recent occasions were in 2012 and 2014. In the former, both sides won 2-1 at home with Bayern winning the penalty shootout to secure a home final against Chelsea, which they went on to lose.
This is the 25th time these two teams have met in UEFA competition – no teams have played either more often. It is the fourth time they have met in the semi-finals of either the Champions League or the European Cup.
Good evening and welcome to VAVEL UK’s coverage of the second of this week’s UEFA Champions League semi-final first leg match between Bayern Munich and Real Madrid. Many would have hoped this would be the final in Kiev at the end of May, but instead we get (at least) 180 minutes of two of the best and most famous teams in Europe coming head-to-head.
