That proves that Manchester United in that period didn't have someone who was able to properly measure the value of a player so in the end they just blindly offered a fantastic price, I suspect it was more than Harry Maguire's market value at that time, and of course for Leicester it was like luck because they don't need to work hard to sell these players like what Man United is currently experiencing.
And I think it's also a good thing to loan the player to West Ham because it means that the player's salary will be the responsibility of the borrowing club, thereby reducing expenses for Man United. Moreover, West Ham has been left by Declan Rice, the two positions are indeed not the same, but if Harry Maguire can return to perform well, then when defended he can replace Rice's role, who also often helps West Ham's defense. Which may be the question whether Maguire will also make mistakes because maybe he will undergo a transformation at West Ham.
The highest market value for Harry Maguire is €70 million and Manchester United signed him for €87 million obviously it's above market value, actually we can't determine whether Manchester United made a mistake when signing him I'm sure they've considered it but what happened is could be due to other factors for example he doesn't fit in the Manchester united squad or his age holds him back. The right choice is to loan him to another club give him another chance to see what his main obstacle. If Man United wants to let him go it will lose more than 50% market value
