Gnabry should be sold while his value is still there. Feels like he isn't in the same tempo as the rest of the team for a while.
Also, Upamecano gives a clownish feeling every game. Dunno if he has problems concentrating, he is slow/dull at times and then responds in a hurry and makes those easy mistakes.
Lewandowski absence is very big for now, the team still creates chances, but there's no one to finish them most of the time.
Mane needs to be fully integrated by winter, if not Bayern doesn't have a chance at UCL this season.
