#2 Harry Maguire

The 6 ft 4 centre back showed in the 2018 World Cup for England just how a proper central defender should command his space. He is tall, strong and an outright bully in the box. The 25 year old will be chasing a big career move, with a move to United an ideal destination in that regard.
Central defence is an issue that has given Mourinho a lot of headaches. It is no secret that Mourinho fancies physically imposing centre backs. Phil Jones, Victor Lindelof and Chris Smalling have many a times proven to be fringe.
Eric Bailly is the only one of United's centre backs who has shown the ability to boldly command the defensive line. He however is injury prone, so bringing Maguire on board will be crucial for United.
The Red Devils had a big problem in defending set pieces last season, having someone like Maguire who understands the game defensively is imperative.
United may be forced to part with nothing less than 50 million pounds in this transfer market where players' valuation has sky rocketed. Leicester City will be compelled to sell if a figure like that is tabled for a defender.
