"It was a very good performance from the boys and we could have scored a lot more than the four we got, but the Carlisle goalkeeper was excellent," under 18's coach Hugh McAulley told the club's official website.
"Marvin took his goals very well and we were able to give all of the squad a game which was the most important thing.
"David Amoo did very well and he was desperately unlucky not to score on the day."
