Keeping a very disgruntled player in the team is not the best option for any team, they then risk selling him at the end of his contract and for free
So I too am confident that Manchester united will eventually let Antony go to Real Betis and continue his career peacefully
Although Antony ultimately joined Real Betis, he is still on Manchester United's list of players who are difficult to sell. Antony, Garnacho, Jadon Sancho, and Hojlund remain unclear about the future of their professional careers. Rumors about potential clubs are circulating daily.
The club has started creating people and systems that are independent of them and even though officially they are not completely out from the club, it is just going to a matter of time before they become history as long as united is concerned. from all indication, garnacho wants real Betis and we have seen how that he had a good time while playing for the club. he wants to stay at Real Betis and not united and with the signing of new players into united, i believe that it is a clear indication that a clear option is already available and right on ground which will make manchester united to survive without them.
