Goals from Juan Mata and substitutes Marcus Rashford and Mason Greenwood secured our first win of the season. Mata, on his 200th start for the Reds, opened the scoring from the penalty spot just before half-time, following a foul on Brandon Williams.
Luton Town gave it their all and it took United until the 88th minute to add a second strike, when Rashford scored with a cool finish after going one-on-one with the goalkeeper James Shea. Greenwood grabbed the final goal of the game with a trademark attack, cutting in from the right with a couple of step-overs before slotting the ball home.
