Mason Greenwood is the first player born after 2000 to score a goal for Manchester United.
The teenager broke his senior team duck with an impressive strike in a 1-0 win over FC Astana.
United created many great chances against their Europa League opponents, but could not finish those moments.
Eventually, a stunning narrow strike from Greenwood's right boot got them ahead.
And they held on to claim all three points.
Greenwood is close to turning 18, and will be hoping to break many more records as he transitions to the first team.
