Fiorentina official Sandro Mencucci has tried to warn off Chelsea by suggesting that Stevan Jovetic is not for sale.
The Blues have been linked with a move for the 22-year-old, who is believed to be considering a switch away from the Serie A side.
"We want to build our future around Jovetic," Mencucci told Gazzetta dello Sport. "He has a contract until June 2016. Being a great player, it's normal that several clubs are monitoring him."
Jovetic scored 14 goals in 27 league appearances for the Italian side this season.
