Not to single you two out, but this sort of commentary is just so tedious and downright stupid at this point in light of the circumstances as we know them.
Has it ever crossed your minds that maybe, just maybe, a guy who's gotten a once in a lifetime chance to play for a club like Juventus and subsequently been branded a failure might want some sort of redemption?
Fucking off to Turkey or France, or wherever, when you think (rightly or wrongly) that you could do better at the club you actually want to play for would be galling.
Fact is, it's not about the money for him. He turned down the same wages in addition to European games to stay.
He's on the heels of a very productive half-season at Parma. Do you really think his plan the whole time was to come back just to sit in the stands and collect a cheque weekly? For what purpose? Just to piss people off? Be serious.
To me, it seems like he's got a point to prove and thinks he can play his way back into the team.
