The England star is currently the fifth-choice centre-back in the squad behind Raphael Varane , Lisandro Martinez , Luke Shaw and Victor Lindelof .
As a result, he is keen on moving on from the club, but United are adamant that he won't be sold until the season ends.
Meanwhile, McTominay has also endured a tough campaign. He was a regular until October when Casemiro took his place.
The midfielder has since struggled for Premier League starts. In fact, he has made just one since being displaced by Casemiro.
Newcastle United and Southampton have made offers to sign him this month but he will have to wait until the summer to leave.
Aside from the duo, Aaron Wan -Bissaka could also head for the exit door.
