RASMUS HOJLUND debuted a new celebration after scoring for Manchester United against Bodo/Glimt.
The Danish forward, 21, bagged a brace to inspire the Red Devils to come from 2-1 down and claim a 3-2 victory in the Europa League.
Hojlund's first goal came on the stroke of half-time as he levelled with a superb finish, looping his effort into the bottom corner.
He then ran to the fans and gave them a thumbs up, before he turned it to a thumbs down.
And the Man Utd attacker then capped the celebration with a throat-slitting gesture.
Many fans will have been confused by Hojlund's actions.

Reacting to Hojlund's celebration, one fan said: "Gladiator Hojlund, he’s such a mood 😭😭🤣🤣."
