3. Scott McTominay

Scott McTominay was in such good form before getting injured that United didn't feel Paul Pogba's absence the way many had thought they would. McTominay won the United Player of the Month award for September and October, which were apt reward for the remarkable improvement he has shown this season.
Even though he is a defensive midfielder, McTominay has played the role of a box-to-box midfielder successfully this season. He has scored 3 goals and assisted 1 in the Premier League, and his goal-scoring ability from the midfield can be very helpful for United against Tottenham as they have struggled for goals lately.
McTominay is expected to return for this fixture after recovering from his injury. The United midfield has looked stale and disorganized in his absence. His return will give the necessary spark to the team, and his leadership qualities could prove very important for United in such an important fixture.
