He's another one of those players who has the technical ability to play anywhere, within reason. Don't know about anyone else, but I love to see players who have that level of confidence and belief in their own ability, and he has buckets of it. Always looking to take the ball anywhere on the field, and that free-kick summed him up. Doesn't even practise set pieces but he is curling one past the keeper to win his team a game away from home. He just has a certain attitude about him that will mark him in great stead for the future. He's certainly been influencing games, but my only doubt surrounding him was whether he has it in him to start winning them games, and he pretty much put that to bed yesterday.
As for his best position, as I say, he could easily play anywhere in midfield. I, personally, believe that his best position is central-midfield, although you can't fault his contribution playing off Lakaku. I haven't seen enough of him coming through the ranks to know what he is like defensively, but I would assume that his positional play would need looking at if he he were going to play deeper. That said, his range of passing and attitude would be ideal for the position in my opinion.
I'd love to see how he would progress at United with the senior players we have here.
