The Reds started the second period with similar purpose, switching the ball relentlessly and stretching the Baggies defence. With only two minutes gone a third goal arrived. After a United attack appeared to have fizzled out, Matty Willock pounced on an errant West Brom header to unleash a punishing drive to put the Reds 3-1 up. It was a goal thoroughly deserved as United's no.8 proved to be an important conduit between defence and attack throughout the game.
An excellent shot from Harrop was then tipped around the post by Baggies stopper Palmer before Goss and Willock again combined to set up Fletcher to nod home his second of the game. 4-1 United.
After the Reds' cut and thrust start to the second half it was somewhat understandable that the pace of the game dropped following the home team's fourth goal. This lull gave West Brom the opportunity to get a foot on the ball once again and after Donnellan's excellent drive was tipped on to the bar by United's substitute keeper Pereira, the Baggies caused momentary worry after Nabi fired home to make it 4-2.
Thankfully, the strike was to prove nothing more than a consolation effort as United saw the game out to notch an important three points and keep Paul McGuinness' side top of Group 2 in the Barclays Under-18 Premier League.
