It's great to read malducato's learning-curve theory.

For Chiellini, I am really impressed by his determination and leadership in the Olympic match against Portugal. It's right that he's still raw and unpolished but I see great potential in him to become a world-class CB and a future Juventus captain after our beloved DP. He's simply a classical Juve-material with grit, determination and sense of team-work.
It'll be prefect if Canna come back and forms the CB with Chiellini. Can benefit Juve immediately and the future also. I think few would blame Canna of jumping the ship when Juve geot demoted if he really comes back. I love Canna.
