The Argentina international evaded the attention of a couple of Bees defenders at the far post to coolly sidefoot home Marcus Rashford's cross, during our 2-1 victory over Thomas Frank's side earlier this month.
Garna's goal came at a key time for the Reds, who were trailing at the break through Ethan Pinnock's header.
But our no.17's sidefooted strike arrived just 90 seconds into the second half and sparked a fightback, with Rasmus Hojlund's similarly delightful dink later securing all three points in what would turn out to be Erik ten Hag's final Old Trafford game at the helm.
