Maguire endured a woeful 2021-22 campaign and while he has retained the captaincy under new manager Erik ten Hag, he is fighting to keep his place in the starting XI ahead of the visit of Liverpool on Monday.
After losing Antonio Rudiger and Andreas Christensen this summer, Chelsea have been rebuilding their backline this summer having brought in Kalidou Kouliably to bolster their options.
The Blues have seen two offers for Leicester City Wesley Fofana rejected and despite the Frenchman being ready to move to London, Leicester are determined to keep hold of him.
United’s first two matches of the season have both ended in defeat – a 2-1 home loss to Brighton on the opening day before last weekend’s embarrassing 4-0 defeat at Brentford.
Ten Hag is understood to be plotting changes to his team for the visit of Liverpool as he looks to trigger a response from his squad.
And Maguire’s place in the team is understood to be under threat with Raphael Varane – who has started the season on the bench – pushing for a return to the team. ten Hag will make a final decision in the next 24 hours.
If Maguire is withdrawn from the starting XI, it would raise major doubts over his future at United under ten Hag.
