It could be said that with Bayern Munich's frequent failures in the domestic league, their chances of winning against Arsenal are decreasing and I think Arsenal with their consistency can bury Bayern Munich's hopes of going further. Of course, the Gunners are very confident with the instability of Bayern Munich so far and they will definitely try as hard as possible to get a win in the first leg.
I know it's not an easy job, especially since the first leg took place at Bayern Munich's home ground. But at least if Arsenal knew the weak points of Bayern Munich's defense then they could steal the aggregate lead first. If this can go well then it is not impossible that Arsenal will break the bad record in history when facing Bayern Munich. It might be a bit naive if we don't discuss this clearly, but Bayern Munich can't do much this season, especially in the Champions League.
Bayern Munich was eliminated from the quarter finals of the UEFA Champions League last season by Manchester City but after analyzing that game, I came up with the idea that Manchester City were able to eliminate Bayern Munich because the German club were yet to get a replacement for their former striker Robert Lewandowski but despite getting a good replacement for Lewandowski last summer in Harry Kane, Bayern Munich have not been able to live up to the expectations of football fans this season especially in their domestic league that Borussia Dortmund is currently leading them.
Last weekend, both Bayern Munich and Arsenal were involved in the strong games in their respective leagues with Bayern Munich facing Borussia Dortmund at home while Arsenal traveled to the home of Manchester City. Bayern were convincingly beaten by Borussia Dortmund despite playing at home while Arsenal got a draw at Manchester City. The results of both teams against strong oppositions last weekend have changed the mind of those who had initially thought that it'll be an easy ride for Bayern Munich against Mikel Arteta's Arsenal. Arsenal will pose a big threat against Bayern Munich and if going by the performances of both teams this season, I think Arsenal might just eliminate Bayern Munich
