The 17-year-old is a huge United fan and was invited to visit their Carrington training ground after his stunning run in the World Championship.
But 'The Nuke' confidently stepped up and hit a 180 maximum with his first three darts to blow them away, sparking scenes of jubilation amongst the watching United players.

Speaking exclusively to Mail Sport, Littler said: 'It was good to see most of the lads, who were fit and who were training.
'I spoke to Scott McTominay and Harry Maguire. Most of the other guys was a handshake and they said "well done". Then I spoke to Erik and he said "it's nice weather" even though it was raining!
'But it was just crazy to meet them and to play against Harry and Christian, that was good fun and I actually felt more nerves in front of them that I did at Ally Pally.'
Littler, who hails from Warrington, shot to fame last month when he reached the World Darts Championship final, losing 7-4 to Luke Humphries.
His performances won him a spot on the 2024 Premier League Darts tour and he'll make his debut - once again facing Humphreys in the quarter-final - in Cardiff on Thursday night.
The eight-strong field also features Gerwyn Price, Michael van Gerwen, Michael Smith, Peter Wright, Rob Cross and Nathan Aspinall.
On meeting Ferguson, Littler added: 'It was crazy to meet him. Obviously my dad and my manager, they've witnessed all of his glory years and 1999.

'I didn't actually get much out of him because of his accent but I did hear him say "stick with it and stick at it."'
Ferguson's glory days seem a long way distant at Old Trafford with Ten Hag's side a lowly ninth in the Premier League and Littler spoke about what he believed is needed.
'It's not the best of times. We certainly need refurbishments I'd love to see some new signings but we just have to get through these bad times and hopefully good times will come,' he said.
'I'd love to see a new centre-half, we were looking at [Jean-Clair] Todibo and Ronald Araujo from Barcelona, and I’d love to sign some next to [Rasmus] Hojlund so he's not feeling that pressure.
'Us United fans look at him being brought in to be our main striker but we actually need someone in front of him.'
