Sampdoria president Massimo Ferrero is urging Patrik Schick not to leave this summer.

It's emerged Schick's contract carries a €25 million buyout clause as Juventus and Liverpool circle.

"His talent is endless: he's cold, clinical and clever," the owner told Secolo XIX. "Every Sunday he's getting better and better. We would like to raise or remove his release clause, I often talk with his agent and I'll go back to it soon. I want to avoid mockery.

"I would like to bring his clause up to €50m but obviously we need to review the boy's contract.

"The world is on his trail, but to leave Samp to go to a team like Juve would be counterproductive for the boy, you can see that he would not play right away.

"If he remains here another year he would become a monster and we are trying to convince him. I would retain both [Luis] Muriel and Schick, but with clauses you know how it works."
