Manchester should release Anthony to Leverkusen so they can generate money off the deal, there's no need keeping him when they can't featur him properly or use him in the right way, and beside Manchester united needs some money to pay the wages and salary of this player, and run the club well fare.
Manchester United do not look like a team that is constrained financially so they may not be in a hurry to release Antony not for financial reasons. Manchester United is a very wealthy team and can actually afford to take care of wages and all of that, they have not made it known if they had problem with all of that to the point they will want to sell of some of their players to be able to get that done.the sales of Antony will not be for reasons of them jn dare need of funds but because either he wants to move or the team may no longer want him with them anymore.
This is a very valid observation. If Antony is leaving the team, it won't be to make money from him. He believes he's no longer a Manchester United player and wants to leave. A team wouldn't hire a player who doesn't want to be at Manchester United. Even though they had a terrible season last year, Manchester United has a history of success and is one of the most established teams in the world. I predict they'll be in a better position in the coming years. They could be in the Premier League title race again, but they'll have to be patient for a few years. If Leverkusen signs Antony, they'll be a truly strong team. Furthermore, the Leverkusen manager is the one who trusted Antony and got him transferred to Manchester United. Therefore, he might want to work with Ten Hag.
