Harry Maguire was definitely never the best defender in the world. Not even for a single moment in his career. He was just simply overhyped. Manchester United got carried away and paid a lot of money to bring him in. Which obviously did not work in favour of them. And now he is just a liability. The coach is coping.
Harry Maguire have no place to play football or handle football position in Old Trafford because he's extensively overhyped. There are core existence of hypes in the football system, unfortunately this is not the lucky end for all these hyping players. We have genuine players that are talented with outstanding performance and we also have those that doesn't belong to the system. Perhapes We are aware of the things happening in the system, the sad incidents that temporarily happen to the hardworking players, everything here is already rigged for their own best interests, any other thing is mismanaged.
Regarding Harry Maguire, I completely understand your point of view. Personally, I think his recent play has been below what you would expect from someone playing for a team like Manchester United. No one is surprised that he's made mistakes, especially last season. Although, I have noticed that he's been a little better in recent games. For instance, he found a way to make an assist in his most recent game. Despite these rare flashes of brilliance, I agree that he has a hard time with Manchester United's tough player competition. Possibly, a club with less tough competition would be better for him. Regardless, I value your point of view and know how frustrating it is when a player doesnt live up to the hype.
