@Salvo, since he's almost surely coming, i'm sure you're asking about how good i think this signing can be for Juve.
Well, i think quite highly of Vucinic, but he is really inconsistent. On his day he can destroy any team, he's very technical, he's a good dribbler and he can make things happen on his own. But like i said, consistency is his problem, imo the main reason for that seems to be that he has mood swings. Sometimes he's in the mood, sometimes he's not. Also i don't think of him as a pure center forward, he's more of a second forward that drifts to the wings. Still, he's an upgrade over Matri and Quag imo, plus he would add more technique and flair to the team. So overall i think he's a good signing that would add quality to Juve.
