Fiorentina director Vincenzo Guerini says they've made a huge offer for Chelsea winger Mohamed Salah.

Although the Serie A club have an option to extend the winger's loan for another year, the Italians also have a clause in which they can sign the player permanently for around £12.5million.

“I tell the fans that the club made an insane offer to Salah," Guerini said.

“If any player, not just Salah, turned down a proposal like that, then it's best he doesn't stay at Fiorentina. However, I think Salah will accept.

“He made a huge impact with us, so it's normal that he should receive calls from elsewhere. He wants to earn more, but Fiorentina made a truly important proposal."
