To be honest, on the playing side i don’t think there is anything sinister.
He simply is from an era of playmakers who didn’t track back, didn’t press, and conserve their energy. The problem is, even on the offensive side, Ozil has been found wanting. So it is not worth the hassle for Arteta to fit him in.
Regarding off the pitch, undoubtedly he is trying to make himself the martyr. He has been roundly criticised by most ex pros in the country, and his tweets and comments are coming from a man desperate to change the narrative. Unfortunately he seems to have the knack digging deeper and deeper, he should have worked for a funeral home.
Incredibly, Partey signing could have given Ozil a slight reprieve. He could maybe have featured in a 4-2-3-1, but again, the issue is not one of effort, he actually runs, but it is almost all solely to get on the ball. He is simply not interested in tracking back and pressing. So that is it for him.
