MANCHESTER (REUTERS) - Manchester United kept alive their hopes of finishing in the Premier League's top four, with two goals from Marcus Rashford and one each from Anthony Martial and Mason Greenwood giving them a 4-0 home win over Norwich City on Saturday (Jan 11).

The result left United fifth in the standings on 34 points from 22 games, five behind fourth-placed Chelsea, who beat Burnley 3-0, while Norwich stayed rooted to the bottom with 14 points.

Midfielder Juan Mata enjoyed a rare league start for United and made the most of it as he contributed with two assists, the first when Rashford met the Spaniard's in-swinging cross at the far post and side-footed it home in the 27th minute.

Rashford made it 2-0 with a 52nd-minute penalty as he drove his spot-kick low past goalkeeper Tim Krul, who had needlessly hauled down United's left-back Brandon Williams with a mistimed tackle.

The lively Mata was at it again two minutes later when he delivered an inch-perfect cross from the right for Martial to head home emphatically into the bottom corner from close range.

Second-half substitute Greenwood put the icing on the cake for the home side with a crisp low shot from 18 metres shortly after he came on for Andreas Pereira.
