BIRMINGHAM - Manchester United kept up their impressive chase for a top-four spot with a comfortable 3-0 win at relegation-threatened Aston Villa in the Premier League. The victory means United, who are now unbeaten in 17 matches in all competitions, became the first team since the formation of the Premier League to win four consecutive matches by a margin of three or more goals. Ole Gunnar Solskjaer’s side are fifth in the table, one point behind fourth-placed Leicester City and two adrift of Chelsea in third with four games left. United went ahead in the 27th minute after a debatable penalty award when referee Jon Moss ruled that Ezri Konsa had brought down Bruno Fernandes just inside the box. The Portugal international rose to convert the spot-kick. Villa keeper Pepe Reina was kept busy, dealing with efforts from Anthony Martial and Mason Greenwood while Fernandes missed a great chance when he headed over when unmarked with the goal at his mercy. There was no dispute about United’s second goal, though, just before the break, a thundering drive from Greenwood after good work from Martial. The 18-year-old has now scored 16 goals in all competitions this season and is rapidly emerging as one of the most exciting young talents seen at United for years.
