Fiorentina is in a race against time to keep Moise Kean as his €52 million (£44m/$60m) release clause is set to expire on July 15.
The Italian club is offering a new contract with an increased salary to ward off strong interest from Manchester United and Saudi Pro League side Al-Qadsiah.
Al-Qadsiah has reportedly offered Kean a lucrative €15 million annual wage, while United continues to monitor the striker, who scored 25 goals in 44 appearances for Fiorentina last season.
If no club activates his release clause by the deadline, Fiorentina plans to negotiate new terms to secure his long-term future.
