Youngster Toby Collyer hooked up with the first team.

Erik ten Hag will be scratching his head ahead of the match, though, with three crucial players missing from training.

The Dutch manager may be without defenders Harry Maguire, Victor Lindelof, and Aaron Wan-Bissaka.

Maguire missed Manchester United’s most recent preseason game against Liverpool.

The trio were not observed in training with the club, and Ten Hag stated that their availability is in doubt.

He stated: “Harry Maguire missed the game as a precaution, and he is a question mark for Saturday.

“So we have training, and we’ll see if he’s fit enough to be available.

“Victor played, but he is still a question mark, as is Azza [Aaron Wan-Bissaka].

“We have to see about [them] tomorrow.”

Ten Hag also announced that Luke Shaw will be evaluated after missing the club’s US tour.

The England international competed in the Euros in Spain and returned to Carrington last week.
