Palermo president Maurizio Zamparini insists Paulo Dybala will only leave for premium price.
The Rosanero patron had previously declared that the Argentinian was worth 42m.
"No-one has met with me about Paulo Dybala," Zamparini insisted to Radio Kiss Kiss Napoli. "42m? Maybe I'll say no 42m might not be enough. Let's see if that moves PSG [Paris Saint-Germain].
"Dybala at the moment is worth too much even for De Laurentiis' Napoli. His price tag is between 42m and 50m.
"I think he'll stay one more year with us if he listens to my advice. We're talking about renewing his contract, he's a very smart guy.
"When he first came [to Palermo] he was with his agents but he wanted to read every word of the contract."
