For the first time, Fletcher addressed Amorim’s criticisms of United’s academy.

Aside from the fact he did not start any academy-produced player in a Premier League game this season, Amorim did not show any sign he had faith in the players it had produced.

In addition, he angered United officials by singling out Harry Amass – whose loan spell at Sheffield Wednesday has now come to an end – and striker Chido Obi for criticism.

Amorim also said he detected a sense of entitlement among United’s young players.

As someone who was himself developed by the club, has previously held the position of technical director and up to this week has been responsible for their under-18s players, Fletcher brought Kobbie Mainoo and Shea Lacey on at Turf Moor.

On only his second senior appearance, 18-year-old Lacey nearly won the game with a curling effort from 20 yards that came back off the crossbar.

“Historically, this club is built around the academy,” said Fletcher. “Our record speaks for itself.

“We’ve got some amazing talent and what I see is a lot of hardworking, humble young players, honest and coachable, who aren’t perfect because they’re young and they’re learning.

“We ask too much of young people in society at times. We have to let them learn – educate them, help them and understand they will make mistakes.

“With good guidance, all of us play a part in developing them to be Manchester United players. Hopefully they can showcase themselves like Shea did.”
