The reports claimed that United are willing to table a £65million bid for Maguire, but will have to offload one of the club's current centre-backs to help raise the funds for the deal.
But he enjoyed an excellent season with the Foxes, trebling his value - with Leicester keen to reflect his growing reputation with a new contract to improve his wages to around £75,000-a-week.
Eyebrows were raised when Leicester paid £17m to sign Maguire from a relegated Hull City side a year ago.
England manager Gareth Southgate is known to have first selected Maguire because of his mental toughness, so he is tailor-made for the constant big-match pressures at United.
