That’s as Erik ten Hag looks to raise transfer funds for a summer rebuild.
TalkSport claims the Red Devils must sell before they can invest heavily in new recruits due to Financial Fair Player rules.
United have no intention of shaking up their squad this month, with just a week remaining in the window.
But Ten Hag has made it clear he intends to sweep away the dead wood to bring in some of his own signings this summer, with Chelsea target Malo Gusto on his list.
And one player in the firing line is axed captain Maguire.
The centre-back has started just four Premier League games this season, and is now fifth-choice in his position after Luke Shaw’s switch from the left.
West Ham are known to be keen after failing with a loan bid for Maguire last week.
And his exit would open the door for Ten Hag to appoint a new skipper.
As for McTominay, he too finds himself down the pecking order at Old Trafford.

Newcastle are hoping to take the Scot off United’s hands.
But after starting in Sunday’s narrow 3-2 defeat at Arsenal, McTominay could yet convince Ten Hag he still has a future at the club.
Indeed, Ten Hag hailed the anchorman ahead of the game, hinting the ace still has a chance of staying.
United’s boss said: “Scott can do the job, he’s a great player for our squad. He’s a great player for this team and I think he’s also making a good development.”
