Daniel James scored on his debut after Marcus Rashford’s brace and Anthony Martial’s strike.
It continued an impressive record for United of winning every Premier League game they have led at Old Trafford (W 264, D 16, L 0).
And the Norwegian put out the youngest starting XI of the weekend.
Talents such as Rashford, Paul Pogba and Jesse Lingard are all products of United’s academy.
And footage has emerged of Solskjaer keeping an eye on the next generation of talent.
In the clip, the Red Devils are taking on Sunderland in U18 Premier League North on Saturday.
They have a 1-0 lead as another attack builds just after half an hour.
“True commitment to the youth”
Man Utd fan
The ball is played intricately between Anthony Elanga, Reece Devine and Max Haygarth.
And the forward curls the ball into the top-right corner.
United fans around the training ground cheer the team, including a group of familiar faces.
Solskjaer can be seen smiling alongside his coaches, including Michael Carrick, on the sideline.
The Red Devils went on to win their season opener 3-0 against the Black Cats.
This footage was shared on the club’s official YouTube channel, where it has been viewed more than 55,000 times.
And the United faithful loved seeing their manager watching the club’s young stars.
“True commitment to the youth,” one supporter said.
Another commented: “Nice to see Ole and co smiling from the sidelines.”
While a third pointed out one aspect the club legend has improved at the club.
“You would never have seen Mourinho there,” they said.
And a fourth added: “True students.”
It comes as the decision not to give Solskjaer this member of staff was branded “pure illogical idiocy”.
