This is the rule of the game, every player goes by the same rule and as juventus fan, I would not see players defecting from the club as traitors as long as we can something back in return. We buy the players the same ways and what goes around comes around.
Everyone looks after himself and I expect nothing less from them. If a player decide to defect from Juventus, I wish him the best, remember the good times and move on.
Micolli is a whole different story, he deemed he was treated like crap because he didn't play every single game and he was loaned out. If he wanted to leave because of that, I think most juventus fans wouldn't care and wish him the best. But instead of requesting a transfer, he just kept *****ing and *****ing over and over again. And up to now, I don't think we see him as a traitor but just an asshole.
