Manchester United put in a dominant performance to beat a terrible Crystal Palace, who have lost all seven Premier League games this season without scoring.
Unbeaten United led within three minutes when Marcus Rashford's excellent work on the left wing ended with a cut-back to Juan Mata, who steered home from 10 yards out.
Their second came when Ashley Young crossed for Marouane Fellaini to volley home from two yards out at the back post.
Fellaini scored his second goal with a close-range header from Rashford's free-kick early in the second half.
Romelu Lukaku scored a late fourth - his 11th goal in 10 United games - by converting Anthony Martial's cross from close range.
The result takes United top for a couple of hours at least, with Manchester City visiting Chelsea at 17:30 BST. Palace remain bottom.
