Fiorentina coach Sinisa Mihajlovic expects big things from youngster Khouma Babacar this season.
Senegalese striker Babacar impressed in preseason and could get more playing time this season.
The coach said: "Comparing him to Mario Balotelli is a compliment. He needs to improve a great deal, as is normal for a 17-year-old.
"I am always on his case because he is a player who can make the difference and I get angry with every player who I know can give more.
"My side must never give up and maintain the constant belief it can win. I want a tough outfit that fights for 90 minutes. I will always run a few risks to win a game, but to do that I need the team to believe in itself."
