I still have hopes that Unai will get the best out of Mesut but ultimately it is down to Ozil himself to decide he's going to play the way the manager wants him to.
If I was to list what I was happiest about at this point it would be that we seem to play with more intensity for longer than we used to. Even in the Liverpool loss we were pushing forward until the end of the match, the heads never seem to go down which I thought was a characteristic of the later Wenger teams. It wasn't just that we got pasted from time to time, it was that when we went behind early on it looked like we gave up and just accepted it.
No sign of that under Unai imo.
