But the 23-year-old Egypt international, who thrived at the Serie A club in a six-month loan last season, would like the terms of his next loan improved if he is to move there for a second spell.
Fiorentina have proposed to Chelsea that they take Salah for a whole season at a cost of ??1m, after the player scored nine goals in 26 appearances from January to May last term, and the Blues are now discussing the deal.
Chelsea signed Salah in January 2014 on a five-and-a-half-year contract from Basel, but has not found a place in Jose Mourinho’s plans, making just six Premier League starts and 19 appearances overall.
Fiorentina recently appointed the former Swansea boss Paulo Sousa as their new head coach after sacking Vincenzo Montella, despite finishing fourth in Serie A.
Salah began his career with El Mokawloon in his native Egypt before joining Basel’s academy. He made 83 appearances and scored 13 goals for the Swiss side.
