Fiorentina have rejected a £20 million bid from Chelsea for Stevan Jovetic.

The Serie A side are keen to hold on to the 22-year-old striker and have snubbed an offer from Blues owner Roman Abramovich, says La Gazetta dello Sport.

With the Montenegro international having signed a new five-year-deal with Fiorentina in October last year, it is thought Chelsea will have to dig deeper if they are to prise Jovetic away from Florence.
