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's position is not in a pleasant condition, especially since several of their main players are still absent due to injury. in particular, the main goalkeeper even though Neuer's performance was actually unstable before he suffered a long injury. if I refer to the information I got, even though there is no real certainty regarding it. however, it is possible that Sven Ulreich will be used as the main goalkeeper when they visit the Gunners' home ground at the Emirates Stadium. If that is the case, as we know, the goalkeeper's performance is very unstable. theoretically, if this prediction fits the scenario. So it is momentum for Mikel Arteta's team even though in football anything can happen.
In the Bayern Munich camp, there are quite a few who are favorites for Bayern to overthrow Arsenal in both the first and second legs. however, it is not an easy job for Thomas Tuchel's team, especially if several of their core players were still injured during the match against Arsenal. however, Tuchel and his team will work as hard as possible to achieve positive results in the match against Arsenal later. I tried referring to the betting options provided by the bookies, if Arsenal are far superior in this quarter-final match. But football is unique, we will know the results after the match is played/finished. so, let's just wait before the meeting between the two teams is held.
