William Keane featured for Manchester United U18 in their 1-0 win at Barnsley.
William and twin brother Michael both signed scholarship forms with United over the summer.
Following in the footsteps of the Neville brothers, Gary and Phil, the duo are avid United fans and have three-year contacts by the end of which they hope to have moved off the Old Trafford terraces and onto the pitch.
Michael is a defender, while William plays as an attacking midfielder and said: "It would have made it difficult if one had made it and the other had not. There's nothing I'd rather do than be a professional footballer. I would love to be able to win the Premiership. When you train it's great to see the United players like Rooney on the next pitch, they are all so good.
"Our parents were delighted as we got offered our new contracts just before our birthday, so we had a double celebration that weekend."
