Juventus general manager Beppe Marotta concedes they would be powerless of Paulo Dybala chose to leave.
The striker signed a new deal with Juve earlier this year.
Marotta said, “Release clauses for Juve players? It’s crucial in a player-club relationship in Spain, but only Higuain and Pjanic had them in Italy. I’m against giving clauses to our players.
“Neymar’s transfer? The damage can’t be calculated that easily, and for me it goes beyond the €220m [Barcelona] pocketed.
“I also take into account that they lost a player like him towards the end of the transfer window.
“Dybala? The player is the one that decides his fate, and if he wants to leave, it’ll be impossible to keep him.”
