It was an early Friday morning start for the young Blues as they returned to league action with the relatively long trip to face Port Vale.
And a brace from new arrival Ethan Henderson was complemented by goals from Jamie Armstrong and Adam Walton as United got the rewards from a game they dominated.
Speaking about the performance, youth boss Eric Kinder said: "I'm delighted for the lads because they played well and they got the goals to go with it.
"It wasn't the best of starts for us because Port Vale were awarded a penalty when Lewis Rooks was pulled up for a push by the referee.
"We got back into it when Ethan equalised, and that was when we really got our game going. Adam Walton put us ahead and Jamie Armstrong gave us a two-goal cushion heading into the break.
"There always has to be a twist, we do like to make things interesting for ourselves, and that came when we gave away a really poor goal just after half time.
"The pleasing thing was that the lads kept doing the good things they were doing and we made it comfortable again when Ethan scored his second of the day."
"This was an important result," he continued. "We're going into a very busy run of games with FA, Youth Alliance, Cumberland Cup and league games to play, so we needed to carry on with where we left off last week.
"The last two results should have given them confidence and it sets us up nicely for this next run of fixtures."
And on striker Ethan Henderson, he explained: "We've brought him in on non-contract terms for the remainder of this year, and we'll have a look at where we're at with it again in January.
"He's still got a lot of work to do - he knows that - but this is a great start for him. It gives us more options and hopefully it will help us in the forward areas of the pitch, which was something we needed."
Team details to follow next week.
