Mason Greenwood scored twice as Manchester United saw off Burnley to close the gap on Premier League leaders Manchester City to eight points.
The 19-year-old watched his thumping opener after the break cancelled out moments later when James Tarkowski rose above Harry Maguire to level.
But Greenwood scored his second with six minutes remaining with a fierce left-footed strike that deflected beyond goalkeeper Bailey Peacock-Farrell at the front post.
City and United have 6 more games remaining.
City is on 74 points while United are on 66.
