Boss Arsene Wenger has pointed to their 2-0 win in Germany last season, which saw them exit to Bayern on away goals after they won 3-1 in London.
The Gunners also beat Borussia Dortmund away in this season’s group stages, so Wenger has a point when he says: "History is important in our belief. We know we can do it."
However, this season’s Bayern is a different animal to that which won the treble last term – they are even more dominant.
So much so that they would have remained unbeaten in their last six Bundesliga matches without a goalkeeper.
6 - Bayern Munich needed so few saves that they wouldn't have lost any of the last 6 Bundesliga games even without a keeper. Consideration.

Bearing in mind Manuel Neuer is the best keeper in the world at the moment – and that, according to our other stats partner Squawka, he is Bayern’s best player so far this season with a performance score of 997 – that is frightening.
Bayern's invincibility comes as a result of several factors - but Pep Guardiola's implementation Barcelona's tiki-taka style makes it incredibly difficult for opponents to get hold of the ball, let alone muster a shot on target.
Their domestic defensive record is incredible - they have only conceded 11 goals in 24 matches, while Neuer has kept clean sheets in 12 of those games.
Good luck getting past or even close to Neuer, Arsenal – you’ll need it!
