Chelsea have had a £20million bid rejected earlier this month but according to La Gazetta dello Sport but they believe a fee of £25m would be enough to secure the 22-year-old's signature. If Chelsea decide on lodging a £25m bid it would meet Stevan's buy-out clause in his contract.
Fiorentina did issue a hands-off warning last week but the move looks a lot closer now as Chelsea are planning to meet his release fee. Juventus and Napoli are also interested in the Montenegro international but a move away from Serie A looks more tempting for the youngster.
