He's an attacking midfielder/support striker. He can play on the wing, but his future lies in the central area with freedom to drift. We may not have his "position" in our side this year which is due to the fact we didn't have the personel. Our midfield this year was played in part by Carrick,
Scholes, Jones, Anderson, Giggs, Park, Rafael, Cleverley, & Fletcher. All of which, despite being a fantastic selection of players, fail to offer the attributes associated with a successful attack-minded midfield playmaker.
Off the top of my head City have utilized Silva, Nasri, Toure, Milner, Agüero, & even Tevez to fill the role between the midfield and striker. All of which are established international players, all are on huge wages, and most would claim the central attacking midfield to be their natural or first choice positions.
