Fiorentina coach Cesare Prandelli praised Dusan Vlahovic after victory over Spezia.

Vlahovic struck in the 3-0 win.

Prandelli said, “Sometimes he breaks down because it's impossible for him to score on every ball.

“The important thing is that he plays for the team.

“He must find the inner serenity. He works with great determination all week. I don't like mood swings during the match.

“From a character and motivational point of view, he is destined to improve.

“Then there are moments when the strikers don't score and that's where the player must grow thinking he's useful for others.

“Let's remember that he's 20 years old and has important margins for a high-level career."
