If the rumor regarding a pay increase is true:
1) He is really one greedy and cheap motherfucker, holding out for 200,000 extra, when he's already making millions
2) He is really stupid. Why risk staying @ Juve and being hated by the fans (not to mention enjoying the view from the stands and not getting any playing time), whereas you can get the same amount of cash playing for another club?
That is why I say this is a BS rumor, a ploy by his agent to try to squeeze more cash from Fiorentina and for himself.
