I think he is too old to agree to sit on the bench. He truely believes that he deserves more than that.
He is very unhappy indeed. In the past couple of years I have never seen him happy after he scores a goal.
Good point. You can't have 4 strikers in the field at the same time. Gilardino, Miccoli, Del Piero + Vieri... sounds a little too much. Bobo is too old to sit on the bench.
I would welcome his return to Juventus though.
