Antony, 25, is one of five players the club wants to sell as soon as possible, along with Jadon Sancho, Marcus Rashford, Alejandro Garnacho, and Tyrell Malacia.
The club sees Antony as a valuable asset, given his strong performance while on loan with Real Betis in the second half of last season.
As a result, Manchester United are now asking for £50 million to sell him, according to reports.
Several clubs have already shown interest in Antony, including RB Leipzig, Bayer Leverkusen, Brighton, Newcastle, and Betis.
