Manchester United boss Erik ten Hag added two youngsters to senior training today.
The Manchester Evening News says Spanish defender Marc Jurado and midfielder Omari Forson trained with the first-team on Monday.
Right-back Jurado participated in the session with Aaron Wan-Bissaka not visible in the imagery that was released by United.
Fellow full-back Luke Shaw was also missing, having sat out two of the last three games. Shaw has not played since August 13 and is currently nursing a minor foot injury.
Forson was also recalled to the training squad to likely offset the absence of Donny van de Beek, who has missed the last two matches through injury.
