Juventus coach Maurizio Sarri admits trying to bring the best out of Paulo Dybala can be a headache.

Sarri hailed the Argentine forward's skills and explained that this is a pleasant headache for the coaching staff.

"Paulo [Dybala] is a phenomenal player," he said ahead of the Old Lady's game against Milan in the Coppa Italia.

"He is a star, although tactically it is difficult to make him coexist with Cristiano Ronaldo.

"It is not easy to get them to play together, but with the technical and physical qualities Ronaldo and Dybala have, they can make a difference at any time.

"The team must adapt to these qualities, but it is also true that the area is a bit empty, although it is a pleasant difficulty."
