He isn't that traditional winger who runs and just crosses from the leftwing. I see him like a creative Nedved. More elegance, less power. He'd be a great replacement.
I have watched some games recently, and I still think Balzaretti is slightly better. Chiellini is the one for the future though and should play alot now in Serie B so that he will be able to become really really good.
I actually think that Chiellini is a security risk, and that he isn't so good with the ball. Balzaretti is a player that I feel I can count on more than Chiellini atm.
:S
Neither of them, lets go for Kaká. Since the 'Dinho is coming to Milan :P
seriously I would want either. Both are really good players and Robben is misused at Chelsea.
