Palermo president Maurizio Zamparini has again spoken of Paulo Dybala's development at Juventus.

Zamparini sold Dybala to Palermo last summer.

“I was sure Dybala would do well with Juventus. He has a great temperament, before signing a contract with us he'd want to read it all beforehand.

“Here is a world-class player, at Palermo he only had Vazquez to speak the same footballing language.

“He'll do very well at Juventus. His bulging muscles? If you become too muscular, you then lose speed. After many years of football I see these things, you must be balanced between power and pace."
