However, Amoruso feels Vlahovic is struggling with the pressure of leading the line for Juve.
He explained to Tuttosport: "I see him as stiff when he starts, as if he feels too much responsibility on his shoulders. He really struggles to get into the flow of play.
"As a substitute, however, he's more relaxed and inspired. In those situations, the limited time available makes him feel freer to try his luck.
"What's missing? Being more present when the team struggles to produce play. Coming forward, becoming a point of reference in building play.
"I don't think there will be a single regular starter. If it were up to me right now, I'd always play Vlahovic. He's physically strong, he scores and creates goals: he's the strongest and most complete player. He just needs to believe in himself a little more, work hard, and trust Igor blindly."
