Sampdoria's president is trying to do the same thing with Patrik Schick too.
Ferrero "His talent is endless - he's cold, clinical and clever.
"Every week 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."
