United are desperately working towards the transfer of Maguire this summer.
It comes after a shoddy season at the back after the Red Devils finished sixth in the Premier League.
It was the leakiest year at Old Trafford since 1978/79 after conceding 54 league goals, with the likes of Phil Jones, Chris Smalling and Eric Bailly failing to put together a strong defence.
Ole Gunnar Solskjaer has demanded a transfer policy change to signing young, British talents and the two acquisitions already this summer fulfil that.

Daniel James and Aaron Wan-Bissaka have joined for £15m and £50m respectively but the Norwegian has made Maguire his next top target.
According to the Independent, United staff members believe the arrival of the Englishman will spur on Victor Lindelof.
The Sweden international was the club’s best defender last year but Solskjaer wants two centre-backs who are comfortable on the ball and are aggressive in a tackle.
It is believed that a Maguire-Lindelof partnership will improve them both, leaving the likes of Jones and Smalling on the sidelines.
However, Leicester are not playing easy and are demanding £90m for the former Hull man, who cost them £17m two years ago.
That would smash the world-record fee set by a defender, currently held by Virgil van Dijk after Liverpool splashed out £75m for him.
Despite the high asking price, United are continuing their pursuit and it is believed that an agreement can be reached worth £80m
And though Solskjaer is demanding in the transfer market, the former Cardiff manager has told executive vice-chairman Ed Woodward that he will not kick up a fuss if business is not concluded this summer.
He said: “I won’t bear grudges if I don’t get them.
“It’s natural to leave negotiations and that side of the business to the ones who have that responsibility.
“My responsibility now is to manage the players and to give my view on which players could improve us.
“I am quite patient and understanding because I know it’s difficult to get transfers over the line these days.”
