Former Palermo goalkeeper Stefano Sorrentino says Juventus cannot afford to lose Paulo Dybala.

Sorrentino played with Dybala at Palermo and is aware of how new contract talks have dragged on between the striker and Juve.

He told La Gazzetta delo Sport: “He deserves this contract renewal! Juventus only gives the number 10 jersey to a certain type of players, such as Platini and Del Piero before him. Not to mention the armband when he is captain. I have always been struck by Dybala's deep intelligence and human values.

“He is a decent, serious boy, attached to family. During the Serie B season he gave up his holidays to take care of himself well from an injury, an attitude he continues to have today.

"The champion starts off the pitch, well before putting the ball at the crossroads. He was good at maturing in character.On the other hand, he would never have reached certain goals."
