U mean the first half of that season? when the fans and the tuz were asking for his head? And the "boos" in the stadium were so hardcore?
From that period I remember Vucinic playing as LW, or LWF at best and working his ass off. Not many boos back then, but media criticized him for lack of goals, somewhat ridiculous since he provided plenty of assists for his teammates. Conte and fans were actually happy with his contribution, but you won't get that feeling while reading GdS or CdS, or other biased Italian media outlet, nothing strange there.
