Actually with the look of things Arsenal may likely be kicked out by Bayern Munich on the champions League quarters finals because Bayern Munich are always more favourable than Arsenal on champions league that's why they have more good history on champions league than Arsenal, although is been a while Bayern Munich meet Arsenal but I think Bayern Munich has more opportunity over Arsenal on that match and also considering the fact that champions league is not like premier League that are more easy for Arsenal to perform really good but in champions league the matches are mostly difficult because all the clubs are very strong, although I'm not disputing the fact that Arsenal is not in there good form but the truth is that Bayern Munich is a very consistent team when it comes to the champions League matches and also if you you check there last meeting with Liverpool you will see how good Bayern Munich is and beating Liverpool at the end, so if bayern Munich could perform that good it may likely not going to take much time for them to win Arsenal. So I would just say that Arsenal should focus more on there premier League matches so that there attention will not be divided.
However, Arteta will not just leave the UCL just because Bayern Munich is favored by many parties, but did you know that Bayern Munich is not like it used to be. It's the same as Arsenal in Arteta hands, so both teams have the same chance of qualifying. Bayern Munich is also experiencing a bit of a mismatch between the coach and the players, plus this season will be his last season with Bayern Munich, or it could also be due to the habit of Bayern officials who fired him early. Don't be surprised by the tradition of dismissing Bayern Munich coaches, because as long as they don't meet their targets, Tuchel will suffer the same fate. Compared to Arsenal today, both sides are solid, both coaches and players. Why is this important? Of course, on the field, synchronization is important to build cooperation, and in playing solidly, Arsenal is clearly superior.
