55' Lazio have everyone sitting deep in their own half as they close down the space ahead of Bayern. The visitors are still dominating possession, but are struggling to find a way through at the moment.
53' GOOD SAVE! Lazio are on the attack again and Alberto cuts back to get away from Goretzka before picking out Correa on the edge of the box. He curls an effort towards the far post and Neuer gets a strong hand to it to push it away.
46' Lazio get us back underway for the second half!
Flick will be very pleased with how his side have bounced back after their performance at the weekend and will be looking for more of the same after the break. As for Lazio, they have a lot of work to do to get back into this game with Bayern already netting three away goals, and they need to get on the scoresheet to give themselves a chance.
Bayern are cruising with a 3-0 half-time lead over Lazio. Lewandowski opened the scoring when he latched onto Musacchio's loose backpass and took it around Reina to put it into the empty net. Musiala then doubled the lead when he nestled a shot into the bottom corner from the edge of the box. Three minutes before half-time, Coman's shot was parried away by the keeper after a quick break and Sane was left with a simple tap-in.
45' + 2' HALF-TIME: LAZIO 0-3 BAYERN MUNICH.
45' + 1' It's brilliant play from Sane as he weaves between the Lazio defenders to open up space on the right before whipping a cross into the box. He picks out Kimmich on the penalty spot, but his shot is straight at Reina.
44' Lazio aren't closing Bayern down as quickly anymore and the visitors are more than happy to just knock it around in their own half. Boateng eventually plays it long to Coman, but his first touch is poor and Reina comes to collect it.
41' Coman pulls away from Patric on the left and he swings a deep cross into the far post. He has Lewandowski and Musiala to aim for, but in the end, it's over both of their heads and bounces out of play.

22' Lewandowski is dropping deep to try and get on the ball and this time, he's picked out by Goretzka. Three Lazio players are quickly over to him though and he's eventually crowded off the ball.

18' The Lazio players are asking for a penalty after Milinkovic-Savic appeared to be tripped by Boateng on the edge of the box as he touched it onto Immobile. VAR is having a look at it but spotted the midfielder was offside in the build-up, so it's only a free-kick to Bayern.
17' Bayern break quickly when they win the ball back, with Lewandowski leading the attack down the left. He pulls it back from the byline for Sane at the near post, who goes for the backheel, but he can't flick his effort on target.

8' It's a great run from Sule into the box from right-back and he drifts past three Lazio defenders to get to the byline. He pulls it back for Lewandowski in the middle, but it's an important block by Milinkovic-Savic.
