Palermo president Maurizio Zamparini insists Paulo Dybala won't leave on the cheap.

Zamparini also is confident of keeping Franco Vazquez.

"Vazquez will certainly renew his contract, but I'd have preferred for it to be sorted out six months ago," said Zamparini.

"As for Dybala, so far offers for him have only come in obliquely, because they know how tough Zamparini can be.

"He is a world class player who is being compared to Javier Pastore, so his price-tag matches the skill: we're talking €40m and upwards."
