Manchester United added two players in their Premier League squad. Phil Jones and Sergio Romero were left out of the initial squad.
While Jones has been recovering from an injury, the goalkeeper was close to a departure.
Ole Gunnar Solskjaer said Romero was back in the squad at Carrington having missed plenty of training while expecting to leave United.
“Sergio is working hard, training. He’s in the group. Of course, he lost a lot of training early on in the season,” the United boss said.
First-team players such as Brandon Williams and Mason Greenwood are on the Under-21 list.
Amad is available for selection after his £37million move from Atalanta in January.
United squad: David De Gea, Dean Henderson, Lee Grant, Sergio Romero, Eric Bailly, Phil Jones, Victor Lindelof, Harry Maguire, Luke Shaw, Alex Telles, Axel Tuanzebe, Aaron Wan-Bissaka, Bruno Fernandes, Fred, Daniel James, Juan Mata, Nemanja Matic, Scott McTominay, Paul Pogba, Donny van de Beek, Edinson Cavani, Anthony Martial, Marcus Rashford.
