Italian media are reporting that Fiorentina have rejected an approach from Chelsea for forward Stevan Jovetic.
It is claimed Chelsea made an initial offer of £21m for the 22-year-old, who has scored 12 Serie A goals this season.
Fiorentina sporting diector Vincenzo Guerini has declared that the player will not be sold cheaply.
Guerini told Radio CRC: “We want to build the team around him, but today the word untransferable doesn’t exist.
“If an indecent proposal were made – and it is possible that one will arrive – we would take that into consideration.”
