He's similar to Chiellini, big guy who can cover for his partner's defensive mistakes and good with passing. Rhodolfo's passing skill is what attracted me, that's why I said with Chiellini and Rhodolfo as CB, Juve will become better in attack and holding position.
I'm still undecided with his defensive skills though (that Corinthians game didn't give much), he's definitely better than Bonucci but my impression is that he's about the same with Barzagli defensively, probably a little bit better.
