That’s according to Sky Sports journalist Kaveh Solhekol.
The England centre-back is thought to be keen on a move to Old Trafford.
But a deal looks to be on hold, with Leicester in no hurry to sell arguably their most prized possession.

It was expected that United would complete a world-record deal for Maguire this week, making him the most expensive defender ever.
But the Red Devils are currently thought to be looking to haggle a lower price, with interest also coming from rivals Manchester City.
And Foxes boss Brendan Rodgers is adamant that he won’t sell the 26-year-old unless either club coughs up enough cash.
The Northern Irishman also says that he will bin any deal if it drags on too long for him to find a suitable replacement.
“There are obviously targets we have in mind if Harry was to move on. But we don’t have to sell and we don’t need to sell,” Rodgers said.
“If the valuation isn’t met, it certainly won’t be allowed to go to the very end because if we did want to bring someone in it would be too late so there will be a point in time where even if the valuation is met, it may be too late.”
The club’s hard nosed approach has left Maguire scratching his head though.
Solhekol claims that the World Cup hero is desperate to walk out of the Old Trafford tunnel each week, just as his footballing idols did for so many years.
“Harry Maguire would be honoured to play for Manchester United and follow in the footsteps of his heroes Nemanja Vidic and Rio Ferdinand,” Solhekol tweeted.

Maguire played in Leicester’s friendly against Scunthorpe this week.
