ERIK TEN HAG has been left “wowed” by Darren Fletcher’s son Jack, Sun Sport can reveal.

The 16-year-old midfielder was promoted by United’s Dutch manager to train with the first team ahead of their clash with Galatasaray.

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 joined alongside his twin Tyler, and the pair are sons of United technical director Darren.

While Jack was not selected as part of the travelling party to Istanbul, he’ll be buoyed to have been selected to train with the first team.

Kobbie Mainoo made a sensational Premier League full debut for United against Everton on Sunday at the age of 18.

And Alejandro Garnacho, 19, scored a stunning overhead kick at Goodison Park and also emerged from United’s academy.

Meanwhile, Sun Online can reveal Ten Hag remains confident United can still have a “brilliant season” despite their European future hanging in the balance.

Our source added: “Spirits remain high. United’s form of late has been good and they still think they can get out of the group, and go on to have a brilliant season.

“New editions will also come in in January which will give the squad and the club a much needed boost.”
