Carlo Ancelotti has stated he does not believe the 5-1 thumping of Arsenal is the true reflection of what happened on the pitch.
Bayern Munich progressed to the last-8 10-2 on aggregate , despite Theo Walcott putting the home side in front in the first half.
The dynamics of the game changed after Bayern were awarded a penalty and Koscielny was handed a red card.
Lewandowski converted from the spot, before Robben and Costa scored one each and Vidal scored a brace.
And Ancelotti believes Arsenal were on top of things before Koscielny was sent off.
“It was not a crazy game, more difficult. Until the penalty the game was really difficult,” he told a post-match news conference.
“Arsenal played really well for 50 minutes, putting a lot of pressure in the game.
“We had difficulty defensively and also with the ball. We did mistakes that we are not used to doing.
“This result doesn’t really respect what happened on the pitch because Arsenal played a really good game.
“With 10 men it was really difficult. For us, the penalty took out all the pressure that we had.
“We started to play with one more man and we scored a lot of goals but, honestly, the result does not respect what happened.”
