There was a small chance, post Newcastle in the league, that I thought he might come good again. But he seems to have convinced himself that he's not good enough to play in the PL. There's nothing about his demeanor that says "I'm going to get stuck in and show them what I can do". His body language is awful.
The physicality in the league has been ratcheted up up some way, even since his good season (when he was very good off the bench and then from the start of games as that season wore on). But the biggest thing is that he is the very epitome of a confidence winger, who has zero confidence.
