Its like he has a mental block when plaing at the highest level.
I know today was not the highest level but he seems to have a lack of confidence in his own ability to make the step up. His career to date highlights this
it's not even that. He's still confident enough to run/dribble at his marker and try to produce a cross, which shows that at the least that he certainly thinks he is good enough.
But the problem is..... he simply isn't.
