I think he has been bought for his adapatability, he can play wide in some matches, just behind a striker, or in a midfield 3! He may even play in a two man midfield at times, if he is given orders not to wander too far forward! Great addition! I would imagine his key role will be in a 3 man midfield against the better teams in the league/ champions league! It was clear last season we needed an extra body in there, particularly in Europe!
