Ole Gunnar Solskjaer has revealed Shola Shoretire and Amad Diallo will likely feature against Leicester City night due to Manchester United 's fixture congestion.
The Old Trafford side are amid a span of four games in eight days as they host the Foxes on Tuesday night, followed by their rearranged Premier League fixture against Liverpool on Thursday and visit of Fulham in seven days' time.
The United boss admitted it was impossible to field a full-strength side for all three games which opens the door for teenagers Shoretire and Diallo.
He said: "They are in contention. They are in the first-team squad, they are training with us every day.
"I would think that some of the young boys will get an appearance definitely. If it's coming on towards the end or from the start I don't know because I don't know how the players will be on Tuesday when we see them."

Shoretire, who has come through the academy set-up, has impressed in training throughout the course of the season and was handed his Premier League debut in a 3-1 win over Newcastle back in February.
And Solskjaer insists he will give opportunities to the players who deserve it regardless of their age and that 17-year-old Shoretire was given a chance over his teammates on merit.
Speaking after the win against the Magpies, he said: "It’s important that our kids know that when they’re good enough, they're old enough.
"Shola has been training with us for a while, done really well and it was next step for him. A few players went out on loan which made the path for him shorter.
"He is a boy we believe in. We wanted to give him a little taste of it (playing in the Premier League).
"Of course the game was not done, still another six or seven minutes but he is a boy we believe in."
