In one way, I don't want Cannavaro since he betrayed us at our hardest times. It would be a bad message to our players if we signed a player who clearly showed that he wasn't loyal to the club. I also believe it would be disrespectful for Del Piero, Trezeguet, Buffon, Camoranesi etc. because these played stuck with Juventus during Serie B time and signing Cannavaro would mean that their sacrifice didn't mean anything.
In the other hand, I believe Cannavaro would be a great signing if we made a 1 year contract with the following of a scouting contract for the future. He would have good influence on the younger players and could be tutoring them. We shouldn't forget that he will turn 36 next season and therefore we shouldn't expect anything more than a backup player from him. He clearly showed his age in Madrid.
Since I'm a Juventus fan who believe that respect and loyality are important, I voted no for him.
