It will be a good business for Manchester United if Maguire leaves now rather than as a free agent because if he continues to stay in Manchester United, he will still be under salary and all will be losses on Manchester United.
Harry Maguire is not entirely a bad defender as he is described or widely seen. I have taken my time to watch Maguire in the England National Team squad and he has alot of confidence . So he might be good under another coach.
Overall, when playing with the England National Team Maguire did look better and solid, but we as spectators will definitely remember more often the blunders he made with Man United, up to the own goal against De Gea. At the club level, inconsistency that occurs more frequently means that Maguire must give up the captain's armband if he survives next season. The reports that he will be released in this transfer window are true, but so far no club has sent an official request to Man United. It seems that the price set by United for Maguire is 50 million, making clubs interested in him reluctant to spend that much money.
Ten Hag is really building United and completely overhauling his squad to face next season, United and Chelsea are the two most active EPL clubs currently in the transfer market.
Maguire was a different person when he was at Manchester United and when he was at the England national team, I think everyone thought the same as me. I don't know why that happens, maybe it's because the pressure at Manchester United is greater so he can't play his best.
In fact at his previous club Maguire actually played well, and when he joined Manchester United he started to show his ridiculousness.
However, he is a good player, it's just that Manchester United is not a suitable place for him. But I salute his mentality, how he is always booed but he doesn't listen to what others say.
