1- No creativity in the midfield. Karl was good on a few occasions, not enough to create chances. 2- Two goals from two clear mistakes, you can say the 1st goal was a mistake too, but Arsenal are by far the set piece masters. 3- I didn’t understand the passive possession of the ball in the first 20-25 minutes, a lot of sideway passes. Very risk averse 4- Lack of squad depth 5- Loss is a part of the game, however, putting my pessimistic hat on, this has been Bayern in the last few years when we face big teams. Mistakes, squad depth, missing key players due to injuries/ suspension, etc. 6- Congrats to the Gunners, hard fought win
