Owner Rocco Commisso says that winger Federico Chiesa can leave Fiorentina for the right price during the next transfer window.
Since turning professional at Viola, the 22-year-old has contributed 29 goals from 139 appearances in all competitions, a return which has also earned him international recognition with Italy.
Manchester United and Chelsea are among the clubs said to be interested in the playmaker, and Commisso has suggested that he may be prepared to do business later in 2020.
Speaking at a press conference, Commisso said: "If Chiesa wants, then he can leave, but only for the figure that we set."
Chiesa, who has two years left on his contract, has previously suggested that he is prepared to remain in Florence for one more campaign.
