Agreed. I actually feel a bit sorry for Mkhytarian - the man's confidence appears to be shot.
Guendouzi I find frustrating. He does some good tidying up stuff, but then immediately looks for a pass backwards or sideways rather than trying to create anything. Xhaka is Xhaka. Torreira is never going to be creative and - as you say - Ozil is a passenger. I've no idea what Ceballos (does that mean 'Onions', btw?) is going to do, since what he mostly did yesterday was fúck up simple passes.
