If you look at Arsenal's performance in the last few games in the Champions League, and especially against FC Porto, they were a bit shaky, I believe, because of lack of experience, when in a big tournament like the UEFA Champions League. So I believe their lack of experience will cost them in this game against Bayern Munich, and Bayern Munich are not a team to be underestimated regardless of their recent performances.
Bayern Munich vs Arsenal will be a tough match when they play in the Uefa Champions League quarterfinal. For me, Arsenal and Bayern Munich's strengths are the same, and they have the same pattern of play, but I think Arsenal is the favorite to win against Bayern Munich in the UEFA Champions League quarter-finals.
I think Bayern is still slightly favorites against Arsenal, Bayern has never failed to advance to the next round when they met Arsenal in the Champions League (4 times).
Arsenal might get 3 points in the 1st leg but most likely they will be eliminated because of the aggregate goals at Bayern home in the 2nd leg later.
But currently Bayern Munich is not as ideal as before, with its current strength, I think Arsenal can still provide its own advantages. I know that when referring to H2H, Bayern Munich has never found it difficult to qualify, but with Arsenal's positive trend, maybe we can see a slight difference in results, depending on the determination of the players. Bayern Munich is indeed the favorite but Arsenal will also definitely prepare ways to give their best. Whoever passes will definitely have much greater potential to get to the final.
For the time being, Arsenal and Bayern Munich are 50:50 for me. Besides, the most exciting big match is Manchester City against Real Madrid. With the condition of each club, it is difficult to guess, but if you refer to the statistics, Manchester City's superiority on paper has a greater chance. But Madrid is still Madrid, which can always bring miracles to the field.
