Juventus GM Beppe Marotta insists defender Leonardo Bonucci is not for sale.

Bonucci has attracted serious interest from Zenit St Petersburg this week.

"It's true that Zenit made an offer for him, but we are counting on him," Juventus director general Beppe Marotta said.

"Leonardo is young and last season was his first experience at a big club. We'll continue with him in the new season.

"We don't want to satisfy the request of the Russian club."
