Jesse Lingard curled home a brilliant effort to round off a 5-2 win, ensuring he finished top scorer on four.
Adnan Januzaj also converted with a neat header whilst Wilfried Zaha again looked good, particularly in the first-half. The result brings an end to United's tour of the Far East and Australia and left Moyes gushing with praise.
"A couple of the young lads, Adnan and Jesse Lingard, who I didn't know as much about, did well and Wilfried Zaha, who has just joined, he has shown what he is capable of in the games he has played," said Moyes.
"I think they will go away from the trip feeling they have contributed to it."
Lingard and Januzaj have certainly put forward a forceful case for remaining at Old Trafford, rather than heading out on loan as almost certainly would have happened if Sir Alex Ferguson had remained in charge.
Yet Moyes' squad is still to take shape given he has not even met Javier Hernandez and Antonio Valencia yet, whilst skipper Nemanja Vidic and winger Nani are amongst those who missed the tour through injury.
The near three-week trip has been an eye-opening experience for Moyes, who now understands the global appeal of the club he has joined from Everton.
"I am taking away the great experience of my first trip with Manchester United in general and what the football club means around the world," he said.
"I have also had a chance to get to know the players and try to settle into my new environment and for the players to get to know me as well.
"They have been working with a great manager for a long time a lot of them, so it is going to take time.
"But I have really enjoyed working with them. They have been incredibly professional.
"I can see why they are champions because of the way they conduct themselves and go about their business.
"I have been very impressed."
Moyes paid tribute to his players for the way they performed on what Paolo di Canio described as a "killer" pitch just six days ago.
He even felt confident enough to introduce Robin van Persie near the end, although his star man could not add to earlier goals from Danny Welbeck, Chris Smalling and Fabio before the youngsters entered the fray.
Yet Moyes is also aware United go back with no new arrivals and the issue of Wayne Rooney, who is expected to be fit for the club's next friendly, against AIK Solna in Stockholm on August 6, lingering.
"I couldn't give you any more update than I have said before," said Moyes, before head to the airport and the flight home.
