United's under-18 side brought a close to their trio of fixtures in Hungary on Saturday morning as they went up against Soroksar SC for a second time.
Goals from Lewis Bell and Kyle Soper gave the away side a two-goal cushion heading into half time, and Liam Lightfoot and Jamie Armstrong added to the tally after the break.
Academy manager Eric Kinder said: "Credit to Soroksar because they pushed us all the way in this game.
"We were very good for the first 20 minutes, and we scored a goal in that spell, but we started to see the effects of what has been a tough few weeks after that.
"The lads started to look leggy, because they've packed a lot in to what has been an excellent fortnight.
"It was pleasing to see them dig in, even though the football wasn't as smooth as we would have liked it to have been, and they defended their penalty area really well.
"Like I say, Soroksar put us under some real pressure, so we were pleased to get to the break with a clean sheet and with another goal to the tally from Kyle."
And the Blues found themselves three goals up with the first kick of the second half when Liam Lightfoot took advantage of a situation which had been discussed a number of times during pre-season.
"It was a great goal," the youth boss told us. "I've spoken to Liam a number of times about looking at where the goalkeeper is standing as he's waiting to kick off.
"We mentioned the fact that if he's well off his line then there's nothing wrong with Liam having a go. In this case the keeper was on his penalty spot, so the referee blew his whistle and Liam went for it. It sailed in.
"Soroksar had plenty of possession after that and we got our fourth against the run of play when Jamie Armstrong finished off a very good break. It was an enjoyable game but it was nowhere near as comfortable as the scoreline suggests."
With the lads heading back to England, with a 2am departure timing from Budapest tomorrow morning, he said: "Monday will be a long day but it's been more than worth it.
"It's been an extremely worthwhile two weeks and the lads have taken a lot from it. The facility is fantastic and it's everything you would expect from a headquarters set-up.
"On the pitch things have come together well and the challenge for us now is to bring that home into our league games.
"From playing teams who do things differently to throwing themselves fully into ballet sessions, which I didn't think they'd do, the lads have been a credit to the club.
"Top marks to the ballet instructor because she's done a fantastic job in showing the lads how beneficial the things she's taught them can be for them within their profession.
"It's been excellent and it'll be with a huge smile that we say goodbye to everybody who has looked after us so well come Monday morning."
Goals: Bell (17), Soper (41), Lightfoot (46), Armstrong (71)
