Fiorentina director Vincenzo Guerini says he expects Mohamed Salah to accept an 'insane' offer made for the Chelsea outcast to remain at the club following a successful loan spell in Serie A.

Salah, 23, joined La Viola in February having been persistently overlooked for first-team duties by Jose Mourinho, impressing under former manager Vincenzo Montella and successfully filling the void left by Juan Cuadrado's departure to Stamford Bridge.

The Egyptian scored seven goals in all competitions during his initial stay at Fiorentina, including an impressive brace against Juventus in the semi-finals of the Coppa Italia.

With doubts remaining over Salah's ability to establish himself at Chelsea, it seems unlikely that he will be content to remain with the Premier League champions this summer after the loan expires on 30 June.

Sky Italia reported earlier this week that the player, supposedly looking to earn an annual wage of £2.1m ($3.3m) from his next loan stint, is eager to remain at the Stadio Artemio Franchi and sporting director Daniele Prade recently confirmed that the feeling was mutual at a press conference to unveil Paolo Sousa as Montella's successor.

Prade claimed Fiorentina had already exercise their option to extend Salah's time in Italy, with Guerini praising his impact and confirming that their offer was significant.

"I tell the fans that the club has made an insane offer to Salah," he told Gazzetta dello Sport.

"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."

Although Guerini seems confident that Salah will opt for a return to Florence, The Mirror suggest that the offer presented does not match his requirements and that the former FC Basel winger is instead edging closer to joining rivals Inter Milan in a deal worth £5m ($7.8m).
