His worst match for Juve.
As Conte said, with the way Siena defended " we needed an individual moment of brilliance to break the deadlock". Vucinic was trying to do exactly that. He tried to dribble, he tried to make complicated through passes etc, but not a single of those 15-20 attempts worked. Not a single one. Unfortunately noone else tried to do it. Or to put it better...the others probably knew that they'll fail even if they tried, so they haven't even tried. That's why we needed someone who could do something alone after we've seen that Mirko can't do it today. Del Piero was the obvious choice. Shame that it wasn't that obvious to Conte.
