80' Oh dear! Bayern attempt to play out from the back as Chelsea press hard and eventually win the ball, allowing Kante space to shoot on the edge of the area. He shifts the ball right but then picks out the top row of the stand behind the goal with a wild effort.
79' Chelsea move at pace, going right to left to find Hudson-Odoi, who cuts inside from to look for a shot. The winger is crowded out, though, and it is James who finally goes for goal, scarcely working Neuer.
77' Substitute Tolisso has now been involved in 11 goals in his past 12 Champions League games (six goals, five assists).
74' A deflection hands Chelsea a corner on the right, but they cannot make the most of the opportunity, with Lewandowski back to head clear.
73' Now James lets fly! Neuer looks to have this one covered, though, as the full-back's sliced shot drops just over the crossbar.
72' CLOSE! Coutinho almost adds a wonderful third! Caballero hardly moves as the Barcelona loanee attempts to pick out the top-right corner with a 20-yard curler, just clipping the roof of the net instead.
69' Disappointing! Barkley takes the free-kick he won and hits the wall. This has been another tough outing for Chelsea.
68' A rare Chelsea foray sees Barkley advance towards the Bayern box, and Thiago's foul gives the Blues a free-kick right on the edge of the area...
67' CHANCE! Thiago must score! Bayern's latest corner finds him completely unmarked for a header, but his effort bounces away off a static Chelsea shirt. Alaba hammers the ball back in, yet Caballero gathers.
66' CLOSE! Zouma nods Kimmich's right-wing corner away but then quickly comes close to deflecting the ball into his own goal. Lewandowski thunders in a shot that clips the defender and bounces wide.
65' Bayern have the momentum again now. A move passes through Coutinho and Lewandowski to Gnabry, whose cross is deflected behind for a corner.
64' Coutinho is straight into the action! He saunters up the left and slides in Davies, whose low cutback is just diverted clear.
63' Lewandowski is furious as Chelsea are awarded a goal-kick. Zouma appears to get the final touch from Davies' latest superb cross, but the decision goes against Lewandowski.
61' MISS! What a chance for Muller! Davies gets down the left and lands a cross on Muller's toe, yet the forward fails to make clean contact and the ball bobbles over the crossbar. Zouma is just in front of Muller and may distract the Bayern man, who is furious with himself regardless.
60' Somewhat surprisingly, Boateng - still moving slightly awkwardly - returns to the field. That is a boost for Bayern, although his continued involvement might now represent a risk.
58' Real concern for Bayern! Boateng beats Hudson-Odoi to a long ball and dives to head back to Neuer, but the defender is in agony as he hits the floor. It looks like it might be a muscle problem, which would surely put his tournament in some doubt. Boateng is receiving treatment.
56' Good work from Caballero again to come from his line and claim a deep Goretzka cross. Bayern are in complete control but have not cut Chelsea open with the same success so far in this second half.
53' Good block! Chelsea are still working out there, even with the tie surely beyond them! Zouma dives in to deny Davies in the area, before Bayern go short with a corner that comes to nothing.
51' Bayern break in numbers after Hudson-Odoi is halted, but Kimmich twice fails to find a team-mate in the centre with right-wing crosses, allowing Chelsea to get defenders back.
50' What a challenge! Further cause for Chelsea optimism! Abraham carries the ball into the Bayern box, holding off Boateng, and then slips a pass left into the path of Barkley. But Thiago lunges in to make a last-ditch interception. Great defending.
49' SAVE! Mount struggles to make the most of a rare Chelsea chance! Emerson sends the midfielder in behind the Bayern defence, yet the angle is a little tight and he shoots straight at Neuer, who holds on this time.
47' Here come Bayern for the first time in the second half. Gnabry gets in down the right and sends a low early cross towards Perisic, but Caballero dives on the ball.
46' Chelsea make an energetic start to the second half, haring into challenges, but they are soon back in their own box attempting to beat the Bayern press.
46' KICK-OFF: Bayern get the game back under way!
Bayern's Flick is on course to become only the third coach in Champions League history to win his first five matches in charge, following Fabio Capello (first six with Milan in 1992-93) and Luis Fernandez (first six with Paris Saint-Germain in 1994-95).
Bayern are on the brink of the quarter-finals after another one-sided half in Munich! Lewandowski netted the opener from the penalty spot and then teed up Perisic for the second, with Bayern attacking over and over again. Chelsea netted through Abraham and had another disallowed but have been completely outplayed.
45' + 2' HALF-TIME: Bayern Munich 2-1 Chelsea (5-1 agg)
45' + 2' What a waste! Chelsea have men forward in the area as they search for an equaliser, but Emerson smashes a corner beyond the box and out on the far side.
45' + 1' Chelsea are looking to end this half on a high. Abraham forces Alaba into a challenge following a long ball up the right, winning a corner.
45' + 1' There will be a minimum of one minute of added time at the end of the first half.
41' James has endured a torrid time in defence but gets forward to deliver a delightful deep cross. Mount is stretching, though, and can only knock the ball back towards the penalty spot, where Alaba is waiting to clear.
40' Almost an opening! Perisic runs James down the left and cuts a cross back to Muller inside the six-yard box. However, the forward attempts to control before shooting and the ball slips away.
39' The German side are swarming all over their struggling opponents! Every loose touch is punished, keeping Chelsea penned in.
38' Bayern are playing with such fluency. Neuer clears from on his own goal line after Boateng's strong backpass, but Bayern keep possession and move up the field in sweeping style. When Kovacic recovers the ball for Chelsea, he has no-one to pass the ball to.
37' James gets lucky! Gnabry runs at the Chelsea box and attempts to tease a pass through for Davies, who has run beyond James. The Chelsea defender turns and inadvertently cuts out the pass, allowing Kante to clear.
35' Bayern are just keeping the ball among themselves for now. They have no need for further goals, but Chelsea are struggling to lay a finger on their opponents.
33' Zouma blocks! Lewandowski fancies another goal with a powerful drive from distance, but the Chelsea defender is in his path.
32' Chelsea have now shipped 20 goals in all competitions since the season's restart in June, with only Norwich City (25) conceding more among Premier League teams.
31' CHANCE! Gnabry comes close to a magnificent third! Bayern are stirred again by that disallowed Hudson-Odoi goal and put together a well-constructed move which concludes with Lewandowski nodding down to Gnabry in the area. Caballero does not move, but Gnabry shanks the shot out for a throw-in.
29' NO GOAL! Hudson-Odoi moves to the left and appears to claim an instant reward! The winger places a fine finish beyond Neuer from 20 yards, but a VAR review finds there is an offside in the build-up. Chelsea cannot even get what would already be a consolation.
27' Hudson-Odoi was really struggling up against Davies and has now switched to the left, with Mount coming over to the right.
26' SAVE! Neuer is worked for the first time! Emerson, one of Chelsea's better performers so far, darts forward and thumps straight at the goalkeeper, although he can only parry. The resulting corner is poor, however.
23' Davies finds more joy down the left, underlapping beyond Muller, but the final ball is lacking this time. Kante cuts out the pass.
22' Now Chelsea can regroup as Mount wins two free-kicks in quick succession. They are still struggling to get over halfway, though, with a long ball forward finding Abraham offside.
20' There is no respite for Chelsea. They break after a cross from the right is cleared, but Emerson's subsequent lung-busting run forward is tracked by Alaba, who wins back possession to start another Bayern attack.
18' CLOSE! Gnabry is looking for a team-mate, but his cross almost drifts in! Caballero is rooted, watching Lewandowski try and fail to get a touch, as the ball flashes past the post.
17' Perisic does wonderfully well to keep the ball in play on the left and lift a cross into the middle of the box. Zouma is up highest, nodding the ball as far as Goretzka, whose awkward attempted volley loops behind.
16' Caballero is forced to dash from his line to clear. Bayern's pace in behind continues to cause Chelsea real problems.
15' Kante avoids a booking for a late challenge on Davies, who just dallies in possession for the first time. He is enjoying himself up against Hudson-Odoi, a former Bayern transfer target.
14' CLOSE! Muller fires just over the top! Once again, as throughout the first leg and this match so far, Davies is heavily involved. He outruns Hudson-Odoi and cuts a pass back to Muller, who only narrowly misses the target under pressure from the edge of the area.
13' Chelsea need a response just to stay in this second leg, let alone the tie. They are pressing high where possible, with Neuer forced to hack a clearance out of play.
12' Davies is very unfortunate! The left-back hares after James in the Chelsea area and looks to have stolen the ball to create a clear shooting opportunity, but he is adjudged to have fouled the Blues man.
11' Lewandowski has now scored 52 goals in all competitions this season, the most of any player in Europe's 'top five' leagues.
8' PENALTY TO BAYERN! Early drama! Lewandowski knocks the ball past Caballero and goes to ground. The referee points to the spot before seeing the offside flag is up. However, a VAR review shows Lewandowski is onside and the spot-kick is awarded.
7' Abraham holds the ball up really well to allow Chelsea to attack for the first time, but that man Davies halts Hudson-Odoi and then beats James in the challenge. Chelsea must take their opportunities to get forward when they arise.
5' Hudson-Odoi is the first English teenager to start a Championss League knockout match for Chelsea since Glen Johnson against Stuttgart in March 2004.
5' Davies gets some joy down the left but cannot pick Lewandowski out with a teasing cross. Gnabry keeps the attack alive on the far side but likewise fails to find a team-mate.
4' It looks as though Barkley might be playing off Abraham up front, with Hudson-Odoi taking up a much deeper role on the Chelsea right, presumably to combat the threat of Davies.
3' Zouma heads a corner clear in the centre of the Chelsea box, before Alaba drags a speculative shot a long way wide.
2' Bayern soon have control of the possession and Emerson is twice worked by Gnabry on the Chelsea left, conceding a corner with his second intervention.
1' KICK-OFF: Abraham gets us up and running!
Want an idea of the scale of Chelsea's task? In the entire history of the European Cup and Champions League, no team has ever won by three or more goals in the first leg of a knockout match away from home and failed to progress, going through on all 92 previous occasions.
Despite repeated links to Liverpool, having informed Bayern of his intention to leave the club, Thiago starts. Willian missed the FA Cup final and has not returned for Chelsea, who are also without Cesar Azpilicueta, Christian Pulisic and Pedro following injuries in that match. They name a very inexperienced bench, while ex-Chelsea youngster Musiala is among the Bayern substitutes.
Subs: Kepa Arrizabalaga, Jamie Cumming, Antonio Rudiger, Olivier Giroud, Michy Batshuayi, Fikayo Tomori, Armando Broja, Henry Lawrence, Ian Maatsen, Lewis Bate, Dynel Simeu.
Chelsea (4-3-3): Willy Caballero; Reece James, Andreas Christensen, Kurt Zouma, Emerson; Ross Barkley, N'Golo Kante, Mateo Kovacic; Callum Hudson-Odoi, Tammy Abraham, Mason Mount.
Subs: Sven Ulreich, Ron-Thorben Hoffmann, Alvaro Odriozola, Niklas Sule, Javi Martinez, Philippe Coutinho, Michael Cuisance, Lucas Hernandez, Corentin Tolisso, Malik Tillman, Jamal Musiala, Bright Arrey-Mbi.
Bayern Munich (4-2-3-1): Manuel Neuer; Joshua Kimmich, Jerome Boateng, David Alaba, Alphonso Davies; Leon Goretzka, Thiago; Serge Gnabry, Thomas Muller, Ivan Perisic; Robert Lewandowski.
Let's get the team news from Munich...
Chelsea clinched qualification for next season's Champions League in the Premier League run-in but then were beaten in the FA Cup final and lost some key men in the process. They have fond memories of this stadium, though, having beaten Bayern to become European champions in 2012.
Bayern are going for the treble, having won the Bundesliga and DFB-Pokal, and have complete control of this tie heading into their home leg. Hansi Flick's side were dominant at Stamford Bridge back in March as they won 3-0.
