Fiorentina president Andrea della Valle has told potential suitors that it will take a huge offer to prise Stevan Jovetic away from the club.
The Montenegrin forward has been linked with moves to Juventus and Arsenal this summer, with a recent report claiming that Manchester City had become favourites to land the player.
However, La Viola chief Della Valle warned Juventus that it will take as much as €30m (£25m) to tempt their Serie A rivals into doing business.
"They can give us €30m cash or nothing at all," Della Valle told Mediaset Premium.
"Otherwise, we'll give him to someone else. It's time to understand whether Juve have the money or not. I think they do. We will not accept players in part-exchange. We will not wait much longer."
Fiorentina recently signed Mario Gomez from Bayern Munich.
