Bologna director general Roberto Zanzi warned they are not ready to release him.
“It’s true, there is a lot of interest around our players and that shows how good they are,” Zanzi told Sky Sport Italia.
“Our project is simple: we want to maintain this basic structure of the team, albeit amid the difficulties of players who are co-owned with other clubs or have personal ambitions elsewhere.
“We received a formal request for Diamanti on January 31, but nothing after that. Juventus have never called Bologna. They probably contacted his agent, but they know it would be difficult to negotiate with us, so they never bothered.
“As of today, I’d say there is a very high chance of Diamanti staying with Bologna.”
