Defensively & effort wise, I can't fault him. But going forward he looks a little lost & very apprehensive. I suppose the fact that he's doing the defensive side allows him the time to hopefully develop in the next few months.
It's a big step up from the level he was playing at, if he was the finished article he wouldn't be with us. I'd give him more than a handful of games before writing him off.
Good summation for me. To be honest, he's offered very little in attack so far and gas given the ball away too many times. Like you say though, he has contributed in the defensive side and I suppose that is an improvement on some of his predecessors.
Far from convinced so far, but let's give him time.
