Fiorentina's director of sport Carlos Freitas says there has been no approach for any of his club's players amid speculation linking Chelsea with a bid for Marcos Alonso.

Chelsea are in the market for a centre-back this summer and Marca reports that they are ready to pay €25 million for former Spain youth international Alonso, while Sky Sports has said they are in advanced talks for the versatile 25-year-old.

Speaking at a news conference to present new signings Sebastian Cristoforo and Carlos Salcedo, Freitas was asked if any enquiries had been made about any of Fiorentina's players, to which he replied: "At the moment, no."

When pressed on the future of Alonso, who spent three years in England with Bolton after leaving Real Madrid in 2010, Freitas added: "He is a Fiorentina player at the moment."

Fiorentina coach Paulo Sousa also said he does not expect any more players to leave the club, adding that he has the word of his club's general manager, Pantaleo Corvino, to that effect.

The Viola could still invest in a player between now and the end of the transfer window, however, with Inter Milan forward Stevan Jovetic reportedly on the verge of returning to the club as they look to bring in new players rather than let any go.

"We want to keep our best players and strengthen our squad and we're going to try to put together the best squad possible for the coach's demands," Freitas said when asked specifically about the Montenegrin.

"We've got to be ready for anything and there are still 48 hours to go [before the transfer window closes] so let's just see what happens."
