Former Juventus president Giovanni Cobolli Gigli admits they'll struggle to replace Carlos Tevez.

Tevez is being linked with a return to Boca Juniors.

"Tevez will be tough to replace if he does leave one day. He is a true world class player and an important element in the locker room too," said Cobolli Gigli.

"I hope in future the Juve directors will focus on young Italian talent and if needs be sell them on for a profit."
