I don't feel it's his aerial game that is the problem. That's one area I would agree that he hasn't had the service.
It's his movement that bothers me (slow reactions) and his lack of confidence in possession. He had one ball deep on the break on Sat, could have carried it 25 yards, but released it (to McCann I think, of all people) after about 5 yards, when under no pressure at all.
As for him being the creative midfielder, I can't see it, whatever he may have done in S America. He hardly ever looks to play a ball forward, or do any damage with his passes. He almost always chooses the simple lay off, and frankly fcuks that up too often for my liking.
