Fully Aggree with this. I dont think hes got the leap or the aggression to make a top notch centre half, and he hasnt got the pace to make a top class fullback, and hasnt got the engine to play in midfield at top level.
All in all hes a decent player who will do a job in a number of position without being outstanding in any.
Being vastly overrated cos hes decent on the ball........... I also heard there same lines about Cahill and look how he's turned out. I agree that he isn't a full back, but i think he'll become a very good CB..
