Arsenal won their record 14th FA Cup on Saturday afternoon, beating Chelsea 2-1 in the final at Wembley.
Mikel Arteta's team had to fight back after a terrible start which saw Christian Pulisic open the scoring after five minutes.
The American ripped apart the Gunners defence, starting a move which saw him play in Mason Mount, who squared to Olivier Giroud inside the box.
He then flicked the ball back to the on-rushing Pulisic, who stepped around Kieran Tierney and finished comfortably past Emiliano Martínez.
That's as good as it got for Chelsea though, as they allowed Arsenal back into the game and two goals from Pierre-Emerick Aubameyang ensured the trophy goes back to the Emirates.
While defeat will hurt the Blues, they will also be worried about the condition of Pulisic, who limped off shortly after half-time.
The young winger picked up a nasty hamstring injury, pulling up as he broke away on the counter-attack.
It was a sight few wanted to see, as Pulisic was the best player on the pitch in the first half and the final wasn't anywhere near as exciting after he was forced off.
But while most football fans were watching on worried, some members of Arsenal Fan TV were actually celebrating the injury.
Yes, seriously. You can see the disappointing footage of the group below:
How low can you get? The clip has since been shared across social media and other fans have been quick to condemn the actions of a few AFTV individuals.
"Absolutely DISGUSTING that Lee and others from AFTV are cheering the injury of Pulisic. Terrible decorum and etiquette," the original tweet reads.
"As an Arsenal fan, AFTV makes me feel sick," another person added, while a third simply said: "State of them!"
Of course, as one of the tweets says, we should give credit to DT and Robbie for refusing to join in the celebrations. But this really isn't a good look for Arsenal Fan TV.
