Odion Ighalo was in Manchester United starting line up as the Premier League giants beat Championship side Luton Town 3-0 to advance to the fourth round of the Carabao Cup.
Juan Mata opened the scoring from the penalty spot in the first half.
Luton attempted an equalizer from Tom Lockyer’s effort but it was denied by United goalkeeper Dean Henderson.
Rashford then scored the second goal in the 88th minute before Mason Greenwood scored his first goal after being withdrawn from the England squad for breaching coronavirus guidelines in Iceland.
Greenwood came off the bench and scored at stoppage time to wrap up victory for the Red Devils.
United remain unbeaten in their last 11 meetings with Luton. Luton last beat United in March 1987 in a top-flight game.
The victory means United will face either fellow Premier League side Brighton or Preston of the Championship in the next round.
