Trezeguet and Camoranesi wanted to leave too,but they were kept at Juventus against their wishes initially.Had the board forced Cannavaro to stay,would he be a hero like Trezeguet and Camo too?I think it comes down to who the board wanted to keep and who they could afford to sell.If peopel call Cannavaro a traitor,which i dont agree with,then maybe Trezeguet and Camoranesi should be called traitors too because they wanted to leave too.The fact that they werent sold was down to the board's decision to not accept any offers for them,not the initial prefernce of Trezeguet and Camoranesi themselves.
Personally,I wouldnt have called Trezeguet and Camoraensi traitors had they left,but there's a thin line seperating their situation and Cannavaro's situation.The board could have not accepted offers for him exctly the same way it chose to do in Trezeguet and Camoranesi's case,but it didnt do so.
