Mason Greenwood, 18, put away two emphatic finishes in Manchester United’s demolition of Bournemouth on Saturday, becoming the first teenager to score 15 goals in a single season for United since Wayne Rooney (17) in 2004/05.

Greenwood’s goals, one scored with the right foot and the other with the left, were scored in the 29th and 54th minutes. Marcus Rashford scored from a penalty in the first half, while Anthony Martial added to the lead at the half-time mark. Bruno Fernandes scored from a free kick in the second half to put United 5-2 up.

The biggest mistake you could make is try to force Greenwood onto his “weaker foot” 😂😂pic.twitter.com/dir3vdmadI

Greenwood is the only teenager in Europe’s top five leagues to have contributed to 15 goals this season.

This was the first time United scored five goals in a home match since December 2011.

United now have three players with 15+ goals in all competitions (Greenwood, Martial, Rashford) for the first time since the 2012/13 season.

With their win, they extended their unbeaten run to 16 matches. They provisionally enter the top four in the Premier League points table, though Chelsea have a game in hand.

In the earlier match on Saturday, Brighton moved to the brink of safety in the Premier League and left last-place Norwich closer to relegation after winning 1-0 at Carrow Road.

In the third match, Jamie Vardy passed 100 career goals in the Premier League by scoring twice as Leicester beat Crystal Palace 3-0 on Saturday to ignite its ambitions to qualify for next season’s Champions League.

By netting for the first time since the restart of the league, Vardy also moved back as the outright top scorer in England’s top flight with 21 goals — two more than Arsenal’s Pierre-Emerick Aubameyang.
