Fiorentina sports chief Pantaleo Corvino has warned Adrian Mutu over his new contract demands.
"In these years he has always shown love for this club, so if he is now making this type of demand it is possible there are other sides behind it."
Although Corvino did not name specific outfits, Mutu has been linked with Roma, Milan, Bayern Munich and Schalke 04.
"I know that Amauri was sold to Juventus for £20m. If someone thinks Adrian is less talented, then he is valued at less than £20m, but vice-versa if he is considered better."
