Fiorentina owner Rocco Commisso has a raft of offers on the table for Nikola Milenkovic.
Corriere dello Sport says Barcelona, Napoli, Juventus and Manchester United have all tabled bids for the defender.
While no sums have been mentioned, the report says all four European giants have made proposals to Commisso for Milenkovic.
For the moment, Commisso has rejected them all, though things could change given the loss of revenue from the coronavirus commission.
Milenkovic, 22, has a contract with the Viola to 2022.
