67' Bielefeld look more positive in the last 10 minutes. That goal seems to have given them a little bit of confidence.
63' WIDE! Coman is found in the box with a great cross from the right, but the winger drags his shot well wide from a very promising position. He really should have hit the target from there!
61' Bayern aren't pleased to have lost their clean sheet and are attacking with renewed vigour. They look determined to increase the gap back to four goals.
57' Bayern win a corner after a spell of safe possession. They've looked a threat from set-pieces so far this evening - can they get another goal here?
55' The second half has continued in much the same vein as the first. Bayern are in cruise control and Bielefeld are, quite simply, outclassed.
53' Goretzka tries to get in on the act as he has a pop from distance, but his left-footed effort is high and wide. It was a bit of an ambitious effort, particularly with his weaker foot.
49' CROSSBAR! How has Lewandowski not got his hat-trick?! A sloppy pass out from the back gifts Gnabry possession on the right. Bielefeld are wide open and the winger has no difficulty picking an unmarked Lewandowski out in the box. The striker takes a touch and goes for goal, but somehow he strikes the bar and sees the rebound cleared!
48' WIDE! Van der Hoorn meets the resulting corner but he can't steer it on target from the centre of the box and it's flicked wide!
47' Doan plays a terrific ball through the lines for Gebauer to latch onto in the box, but the angle is a little wide and Neuer charges the shot down! That pass was outstanding.
46' We're back underway for the second half!
Neuhaus will have expected his side to be second-best in this contest, but they need to make Bayern work harder for their dominance. The visitors have hardly broken a sweat and are picking Bielefeld apart at their leisure. If things don't change, the scoreline could get very lopsided in the second half.
There goes the half-time whistle! Bayern have been utterly dominant so far and they've hardly gotten out of second gear. Muller opened the scoring after his pass rebounded to him in the box, before Lewandowski struck twice from the edge of the area to make things comfortable. Bielefeld's one genuine chance came from a long ball over the top for Klos, but Alaba and Neuer smothered the danger between them. It's 3-0 to Bayern at the break!
45' + 2' HALF-TIME: ARMINIA BIELEFELD 0-3 BAYERN MUNICH
43' Doan goes for the bottom-right corner again with another left-footed effort from distance, but Neuer holds on once more. It's an almost identical effort to Doan's earlier attempt.
41' Gnabry think's he's found Muller behind the defensive line, but the flag goes up for offside and Bielefeld have some respite.
39' Bielefeld have weathered the storm and Bayern have simply reverted to keeping possession with ruthless efficiency, working the ball around calmly as they wait for the right moment to strike.
37' Bayern are really piling the pressure on the Bielefeld goal now. The hosts are just clinging on under a barrage of Bayern attacks.
35' OVER! Bayern win two corners in quick succession and the second sees Tolisso find Lewandowski, but the striker's looping header has a little too much on it and it drops just behind the goal!
34' SAVE! What an effort by Tolisso! The midfielder picks the ball up well outside the box but takes on the shot and catches it beautifully, sending it arrowing towards to top-left corner, only for Moreno to make a fine save!
33' Doan gets to the edge of the area, cuts inside his man and curls a low left-footed shot towards the bottom-right corner, but it's a comfortable save for Neuer.
31' CHANCE! Huge chance for Bielefeld! Alaba slightly misjudges a long ball forward and Klos latches onto it in the box. The Austrian slides in and gets a nick on the ball - just enough of a distraction to hold the striker up until Neuer arrived to claim it!
29' SAVE! Bayern find joy down the left again and Hernandez stands the ball up for Lewandowski to attack. He climbs well to meet it and heads firmly at goal, but Moreno is equal to the effort this time and keeps it out!
27' Coming into this game, Lewandowski had a league-high expected goals value both in 2020 (17.9, 20 goals) and this season (4.4, 5 goals). He's scored with his second shot tonight.
23' Alaba plays a sumptuous ball over the top for Muller in the box, who lays it off for Gnabry in a dangerous position, but the flag goes up for offside.
21' Gnabry has had Lucoqui's number so far and the left-back has been lucky to escape punishment for his clumsy defending. The Bielefeld defender has hold of Gnabry's arm as the Bayern winger ghosts past him with the ball and into the box, but gets away with it.
19' Pavard gets forward from right-back and is felled in a dangerous position by Lucoqui. Bielefeld manage to repel the danger from the set-piece, but Bayern have possession back once again.
17' Bayern work and win another corner, which is aimed at Goretzka, but the midfielder can't make the most of it and it's behind for a goal-kick.
15' SAVE! It's nearly a second for Muller! Bayern work the ball down the left with ease and precision and it's lofted into the box for Lewandowski, who meets it with his head at the near post. However, he can't get it on target and it flashes across goal for Muller, who turns the ball goalwards at the back post, but Moreno is across quickly to block the shot behind!
13' CHANCE! Alaba strolls out from defence and plays the ball down the line for Hernandez. The defender crosses into the middle for Tolisso, who finds himself unmarked as he makes a run from deep, but the header is planted straight at Moreno!
10' Bayern's extraodinary run of goals scored in league competitions is extended further. They have now notched a league-high total of 68 Bundesliga strikes in 2020 - Dortmund are a distant second with 50.
7' It's been very patient from Bayern so far as they work the ball around slowly and methodically in search of openings. No real sense of urgency just yet.
5' Tolisso sends the ball into the middle and Muller meets it at the near post, but his flicked header comes off a Bielefeld defender and the ball is cleared away.
3' NO PENALTY! A lovely long ball over the top sees Gnabry get in behind down the right. The winger controls the ball in the box and is bundled over from behind before Lucoqui puts the loose ball out for a corner, but the referee isn't interested in awarding a spot-kick despite Gnabry's incredulous protestations!
1' We're underway in Bielefeld!
Meanwhile, Bayern have only dropped seven points across their last 43 Bundesliga games against promoted sides (W40 D2 L1), scoring in every single match (133 goals). Additionally, they have only failed to score in two league games since October 2018, scoring 189 goals across 64 games - more than any other side across Europe’s top five leagues during this time.
Bielefeld are still unbeaten at home in all competitions in 2020 (W8 D2) and have kept a clean sheet in all eight of these wins. However, they last took points off Bayern in the Bundesliga in 2006, having lost each of their last five league meetings, scoring once and conceding eight.
Meanwhile, Bayern head coach Hansi Flick makes four alterations from the team's last Bundesliga fixture, a 4-3 win over Hertha Berlin. Chris Richards and Joshua Kimmich are not in the matchday squad, while Boateng and Davies feature on the bench. Pavard, Sule, Tolisso and Coman are all drafted into the side in their places.
Bielefeld boss Uwe Neuhaus makes three changes from his side's 1-0 defeat to Werder Bremen last time out. Cordova drops to the bench, while Cedric Brunner and Cebio Soukou miss out altogether. De Medina, Kunze and Gebauer come into the side.
Bayern Munich substitutes: Alexander Nubel, Alphonso Davies, Marc Roca, Jamal Musiala, Javi Martinez, Jerome Boateng, Eric Maxim Choupo-Moting, Douglas Costa, Bouna Sarr.

Last season's second-tier champions host the winners of the top flight after a solid - if unspectacular - start to life in the Bundesliga, picking up four points from their first three games. Meanwhile, Bayern have already suffered a defeat and will be keen to return to the upper reaches of the table from where they sit in seventh - albeit with tonight's game in hand.
