Fiorentina director of sport Pantaleo Corvino believes winger Adem Ljajic is showing "extraordinary potential".
Ljajic, 18, joined Fiorentina from Partizan Belgrade for €6.5 million in January after Manchester United pulled out of the signing late last year.
The Serbia Under-21 international has scored two goals in three appearances this season, and Corvino believes he could be a star of the future.
"He is showing that he has extraordinary potential," Corvino said. "Now he must confirm that he possesses extraordinary qualities. This is our hope. Anyway, he is on the right path."
