What if Bayern Munich lost out in their league just to get ready to play against Arsenal, let's not forget they they have a very good record against Arsenal and their performance in the champions league can't be compared to that of their league because even when they were playing very poor in the league they still came back to beat Lazio 3:0 to book their ticket to the quarter finals. Arsenal is in good shape and form now but they need not to underestimate Bayern Munich because they will come all out to ake sure they get a win in their first leg and if they are able to achieve that, you won't believe what the final score will be in the returning leg because they will be aiming to facing the next opponent and their confidence will be back. All the teams in this stage is good but is t is still very impossible to know the team that will be champions but after the semi finals the best two will come out from there.
The team that has made it to the quarter finals is the best at the moment, no one should underestimate it and no one should be underestimated. They really understand the atmosphere of the Champions League, where a small mistake can wipe out their chances of progressing to the next round. Arsenal is indeed in impressive form, but they cannot necessarily beat Bayern easily.
Bayern has a wealth of experience when playing in the Champions League, they also have coaches and players who have won the trophy. Arteta certainly understands this very well, and the head to head record can be used as a valuable lesson that Bayern should not be underestimated at all, even though they are currently experiencing a decline in performance in the Bundesliga.
I assume Bayern can still show a different performance in the Champions League, and it will be quite easy for them to recover from defeat. If you look at the strengths of Bayern and Arsenal, in fact the two teams have strengths that are not much different. Arsenal will try their best to break their bad record when facing Bayern, and Tuchel's squad will try to protect their only chance of winning a trophy this season.
