David Moyes continues to be impressed by his youngsters despite the narrow 3-2 loss to Yokohama F·Marinos.
Jesse Lingard, Adnan Januzaj and Michael Keane were promoted from the Under-21s to travel on the 2013 Tour presented by Aon while Wilfried Zaha is bidding to make an impact following his move from Crystal Palace.
After Lingard scored his third goal in the last two games with a close-range effort, following a fine run by Zaha, there was plenty to admire from a team where the average age was only 23.
When asked if 20-year-old Lingard is knocking on the first-team door, Moyes replied to MUTV: "He is. It was a tough game for the young boys tonight and it was probably as young a team as we could have put out with Wilf, Adnan and Jesse starting the game.
"We wanted to see how they do and they're all doing well. It was a hard game for them - one of the best pitches I've seen, a full house again and a wonderful stadium - so it's great experience for those young players.
"I want to see how they can do and I want to give them opportunities because it becomes harder when you're going back and the games are of a more serious nature. This is their opportunity and they're not disappointing me. The young players are doing well.
"Wilf did [set up the opener] and created another good chance for Jonny Evans to make it 3-1 but he put it past the post. He's shown really good signs but we'll keep working on him. He's settling in, like me, and getting to know everybody but he's doing a good job at this moment in time."
As for the defeat, the boss was upset with the defending for the three goals and felt enough chances were created to win the game.
"I'm disappointed with the goals we conceded," he admitted. "We had a lot of opportunities to finish
