Manchester United added insult to injury for Arsenal and Mikel Arteta after knocking the Gunners out of the FA Cup with a barbed post on social media.
The club first issued a one-word response to their shootout win, simply posting on X: 'Justice.'
This appeared to be in reaction to Kai Havertz's crucial shootout miss, who was at the centre of controversy throughout the game.
After going down softly to win a penalty in the second half, cameras seemed to catch Harry Maguire brandish Havertz a 'cheat' before a mass brawl erupted between the two sets of players.
