The condition of the two teams that are still unpredictable in terms of performance I think it could be another factor that this match is difficult to predict.
In terms of mentality and experience now it is certain that Bayern are still very favorites, it's just that with a slightly monotonous way of working and Arsenal's insistent play in a match this could be a differentiator where we know Arsenal's youngsters sometimes become very solid and can play with good consistency in 90 minutes of the match.
Tuchel knows how Arsenal are in a match and on the other hand Arteta must also have known what to do when facing Tuchel later. I just hope this match goes well because after all this is a big match and I expect good tension in this match.
Bayern Munich and Arsenal are indeed a very interesting match, because in terms of strength Arsenal can still be overshadowed by past defeats. But for Arteta, that is not a reason to withdraw before playing. Tuchel may have studied Arsenal and Arteta, vice versa so I think this match will definitely be difficult to predict. Apart from the public who definitely favor Bayern Munich as the strongest team, once again the situation and mentality of the Arsenal players is in a favorable condition. This match will not be easy for Bayern Munich to pass.
Actually for now is a situation that is actually very complicated for Arsenal because they have waited long enough to be in the Champions League but on several occasions at this time they are faced with unlucky when the group phase goes well but for the further phase they actually face some big clubs that make their probability shrink.
Currently against Bayern is indeed a complicated situation because looking at the strengths possessed as well as the conditions, especially for the problem of experience and h2h, they are not favored for this meeting, besides that even if they can win for the semi-finals they will also face a more difficult match if in the quarter-finals Arsenal managed to win and indeed this can still be won especially for Bayern their Quarter-final curse is still unbreakable.
There is a segae wind for Arsenal now because Neuer is likely to rest for a slightly longer period of time because he is injured again now and this can be maximized well by Arsenal because it becomes a little advantage when facing Bayern later.
