Manchester United assistant Mike Phelan is desperate for Harry Maguire to arrive at Old Trafford.
Phelan coached the centre-back during his short stint as Hull manager, making him a regular in the first-team.
Maguire has continued to develop at Leicester City, leading to interest from both United and Manchester City.
The Mirror says Phelan is now pushing the club to prioritise the signing of Maguire this summer.
The report claims the Foxes have rebuffed United's opening offer of £70m.
The King Power club want at least more than the £75m Liverpool paid for Virgil van Dijk in 2018.
Maguire is determined to push through a move, despite signing a new five-year contract last summer.
