Napoli have reportedly set Arkadiusz Milik's asking price at £14m, despite the forward's contract being due to expire in the summer.
Milik has not made a single first-team appearance this season after opting against penning fresh terms at the Italian outfit.
The Poland international will be able to hold discussions with foreign clubs in January as they contemplate signing the player on a free transfer.
According to Goal, Napoli are currently only prepared to part ways with the 26-year-old in January if one of a number of interested clubs pay £14m.
Milik, who has been in Naples since 2016, has previously revealed that he wants to take on a new challenge.
