Goals from Bruno Fernandes, Mason Greenwood and Paul Pogba ensured we returned from the West Midlands with all three points, and extended our excellent away record against the Villans.
It was a slow opening at Villa Park, with United dominating possession in the early stages, but the hosts creating the main opportunities. However, efforts from Anwar El Ghazi, Douglas Luiz and Jack Grealish failed to hit the target.
The Reds picked things up after the drinks break and, after Trezeguet brushed the outside of the post, United opened the scoring via the penalty spot.
It was Fernandes who was fouled by Ezri Konsa just inside the area, and the Portuguese international - not Rashford, who scored from the spot against Bournemouth last time out - stepped up and coolly slotted it past Pepe Reina on 27 minutes following a brief VAR check.
