He is an attacking midfielder who is best at combination play around the box and good movement to get on the end of things. However there are dozens of players around Europe you would rather have in an attacking midfield role ahead of him, including a handful already at Utd.
So no future at Utd in his natural role, going to have show he can play in a deeper role to make an impact. He wasn't bad tonight, he has rarely been bad for Utd to be fair, but he is never really good either, just there, on the pitch, forgettable.
