Well,since he arrived he is constantly improving.
He provided 2 assists so far and made another 2 assists for disallowed goals(Trezeguet against Bergamo and Amauri against Cagliari).Pretty good for someone who naturally is a CB.
I wouldn't mind buying him so far,he is young,aggressive and has loads of potential.I'd even try him as a CB every now and then,maybe we already have the Cannavaro/Legrottaglie replacement?
