Vucinic was on target during the 8-0 win over Lega Pro side Cuneo on Friday and had a hand in three other goals.
“There is so much enthusiasm in the air, both from the players and the fans,” smiled the new €15m signing. “I have rediscovered my smile, which went missing lately at Roma, so I am very happy. I missed that feeling.
“I’ve been struck in the first few days of training by how easily the Coach and my teammates have allowed me to settle in. I feel like one of them already and am at their full disposal.
“It’s wonderful to play with the Juventus jersey on my back. The Coach expects a lot from me and I’ll try to give my all, as I always do.
“That’s all I can do, as after that others will judge my performance.”
