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.
Yes, it's true that when Arsenal played against Porto, they seemed to be experiencing difficulties and Arsenal's success in getting rid of the Portuguese representative was thanks to a penalty shootout. So actually Arsenal didn't appear that strong in the Champions League because perhaps they lacked experience in this competition, especially against the Bundesliga giants who participate in the Champions League every season. of course Arsenal lost to the experience of Bayern Munich. And if you look at Bayern Munich's footsteps, they slaughtered Arsenal with a score of 10:2 in the 2016/17 Champions League season, so this is a worry for all Gunners fans when they meet Bayern Munich later.
But the Arsenal that used to be is not the Arsenal that is now. Arsenal has a big strength in the Premier League so this can be used as a benchmark so that Arsenal gives a surprise in getting rid of Bayern Munich in the quarter-finals because Bayern Munich's performance is also no longer the same as it used to be and this season too. Bayern Munich is experiencing a decline so Arsenal still has a chance to beat Bayern Munich and create a big aggregate when they are at the Emirates stadium.
