The 26-year-old has been a useful figure for United so far this season, featuring in six matches in all competitions and, according to The Daily Star,Ten Hag has demanded the club keep him until the end of the campaign at least.
McTominay may have given his chances of earning more playing time under Ten Hag a huge boost last week when he came off the bench to score two late goals, bringing them back from 1-0 down against Brentford to steal an important win.
