And sources close to the club say Ten Hag is keen to “fast-track” Fletcher’s progress.

Our source said: “Erik Ten Hag has been watching Jack closely for several months now and has been really impressed. He thinks he has huge potential which is why he decided to promote him to train with the first team last week.

“Ten Hag is now working with his staff to put a plan in place to try and develop and fast-track Jack’s progress.

“He is likely to go out on loan next season but Erik believes, in the long term, he has a massive future at United. He’s been wowed by his attitude, and his maturity and – thinks he is the latest in an exciting crop of talent to be coming through at United.”

The 16-year-old, who was the only Under-18 representative in the group, joined United from rivals Manchester City earlier this year.

Jack and his twin Tyler, who are the sons of United Technical Director Darren, also joined.

Jack will be encouraged to have been chosen to train with the first team even though he was not chosen to travel to Istanbul.

At the age of 18, Kobbie Mainoo made an incredible Premier League full debut for United against Everton on Sunday.

Additionally, Alejandro Garnacho, 19, who came out of United’s academy, scored a spectacular overhead kick at Goodison Park.
