Romelu Lukaku was back on the Manchester United scoresheet as they won 2-0 at FA Cup opponents Derby County on Friday night.
After losing to Derby's Championship promotion rivals Bristol City in the Carabao Cup, United boss Jose Mourinho wanted to make sure there was no repeat and named a strong line-up, even though he made five changes.
A replay looked on the cards before Lukaku laid the ball off to Jesse Lingard, who took a touch and sent a 20-yard shot on the bounce into the top corner.
And half-time substitute Lukaku sealed the win after playing a one-two with Anthony Martial to cap off a counter attack.
United striker Marcus Rashford had hit the post in both halves - with a close-range header that he should have buried and a fierce shot across goal.
Rams keeper Scott Carson was excellent, making eight saves, including fine stops to keep out Juan Mata and Paul Pogba free-kicks.
