Arsenal seem to be in a free fall, collapsing at the latter parts of the game against Brighton, as they threw away a 1-0 lead to eventually lose 2-1.
Brighton came back thanks to some heroics from their forward Neal Maupay, who scored the decisive goal.
Arsenal's already very slim chances of getting into the UEFA Champions League have now been dealt an even bigger blow, leaving them lingering in 9th place, possibly going down to 11th by the end of the gameweek.
Whilst they were the better side in the first half, they suffered an injury to Bernd Leno, with the German landing awkwardly after a collision with Maupay.
The German was furious with Maupay, shouting at him whilst he was being hauled away on a stretcher. Leno has been one of the best performers in the whole Arsenal side this season.
In the second half, the game was much more open, with Nicolas Pepe' moment of magic breaking the deadlock in the 74th minute. The Ivorian cut inside and curled the ball elegantly into the top corner.
However, Arsenal's lead lastly just eight minutes, as Lewis Dunk equalised after the Arsenal defence didn't deal with a low cross from a short corner.
Maupay grabbed the headlines even more, scoring in the final minute of the game, a goal that could prove to be vital in Brighton's race to secure a spot in next season's Premier League.
At the end of the game, Matteo Guendouzi could have earned himself a ban, grabbing Maupay's neck, leading to a scuffle between the two sides.
Arsenal are now ninth, eight points below Chelsea who are in fourth place, with the Blues set to play on Sunday, meaning Chelsea could have an upperhand of 11 points.
A win for Chelsea would mean that Arsenal would be closer to 15th place rather than to fourth.
