Forwards: Romelu Lukaku, Anthony Martial, Marcus Rashford
This combination is ideally United's best attacking threat if form and individual talent is anything to go by. Lukaku has scored some goals in the last few matches and that should be enough to earn a starting berth. He could also be used on the right wing which he has shown to be also effective.
Rashford is United's main man who can start either on the right wing or down the middle. His pace will be a threat if he finds the space. Martial on the other hand just recently returned to the fold after some time out with an injury. The Frenchman prefers to play in the left wing where he can attack freely and run at defenders.
He should be fit enough this time around after coming on as a late substitute this time around. If United's front three play as a unit, then they should be able to get the goals that they need to succeed in this type of match.
