Manchester United scored three first-half goals for the first time in the Premier League since January as they swept Burnley aside at Old Trafford to move back into the top six.
Scott McTominay's eighth-minute curler from the edge of the area was United's quickest top-flight goal since the Scot scored twice in the opening minutes against Leeds more than 12 months ago.
Jadon Sancho's deflected effort doubled the hosts' advantage before Cristiano Ronaldo - who had wasted a glorious chance after being sent clean through when the game was still goalless - tapped into an empty net after McTominay's shot had been touched on to a post by Burnley keeper Wayne Hennessey.
