#4 Anthony Martial
The Frenchman, when fit, is one of the first names on the team sheet of late. However, like Lingard, Martial was injured in the game against PSG and it can be said that his absence was dearly felt in that game.
The fact that he has missed the Chelsea and the Liverpool game - both extremely crucial ties for Manchester United - shows the extent of his injury. Now, with an ever growing injury list, Solskjaer will be hoping that he can recall his mercurial Frenchman soon enough as United struggle to put 11 senior players on the pitch.
When Martial starts from the left, Manchester United are a totally different team. The Frenchman's partnership with Luke Shaw has blossomed to a level of brotherhood - the two of them complement each other brilliantly. And the Frenchman's movement and precision on the ball from the left hand side is unmatched right now.
The Manchester United left side is perhaps their strongest area of the pitch and Anthony Martial is the star of the show from there. His performance across the front three, of late, has been nothing short of brilliant.
As such, his Norwegian manager will be desperate to have him back, because Martial's absence jeopardizes most of Solskjaer's plans.
