Bayern is not doing well in the Bundesliga, while Arsenal is doing better.
This is exactly correct, if you take a look at the head to head between the two team, Bayern have won far more games and if we are to predict this game using that, then the advantage is with Bayern Munich. Having said that, Arsenal have improved greatly since the last time they met Bayern, and even though it sounds strange to say, they (Arsenal) are the favorites in this tie as they have the quality to eliminate Bayern Munich.
The quarter finals are the best opportunity for Arsenal to prove their quality, with their performance on fire whether they are able to beat Bayern Munchen. It is difficult to predict the final result of this match, it must be admitted that Bayern Munchen status is no longer favored due to a number of bad results in the Bundesliga. Meanwhile, it would be a shame if Arsenal again failed to continue its mission, because as we understand, Arteta squad is currently in its best performance.
On the other hand, the course of the match might make things easier for Arsenal in the first leg, because they will act as hosts. However, I feel that it is not an easy job to beat a team like Bayern Munchen, Arteta and his players have to work harder than usual. Apart from that, Tuchel is certainly very ambitious to bring his squad to the final, because it is no longer possible for them to win the Bundesliga trophy this season.
