Palermo president Maurizio Zamparini has urged Juventus coach Massimiliano Allegri to show Paulo Dybala greater support.

Dybala was sold by Zamparini over the summer to Juve.

The Rosanero owner said: "Juve must believe in Dybala, Allegri must believe in him.

"When I saw him on the bench in the Super Cup and the first round of the championship, against Udinese, it hurt me. I was amazed and wondered: why did they buy him?

"I texted (Beppe) Marotta and I wrote: pair Dybala with (Alvaro) Morata and you will dominate. These two can blow up all defences, but do not harness them in excessive tactical rigors. If you do that, you lose 50% of their potential."
