Beforehand, there a commemoration of the tragic Munich Air Disaster's 66th anniversary, this being the closest home fixture to the date.
Once under way, Hojlund opened the scoring midway through the first half, extending his Premier League run to four in his last four outings, and giving the Reds a crucial lead in the game.
Ten Hag's side created multiple opportunities throughout the half, but it was only after the break when the lead was doubled, this time through a neat cut inside by Garnacho and kind deflection from his strike. Garnacho added a third, following a driving run by substitute Scott McTominay, with six minutes left of regulation time.
