Neal Maupay stunned Arsenal with a late winner in the Premier League's only 3pm kick-off on Saturday.
Brighton scored twice in the last 20 minutes as they came from a goal down to grab three vital points in their battle against relegation.
Players from both sides clashed at the final whistle as tensions boiled over. On Arsenal's part that may have been due to the costly late concession but also that their goalkeeper, Bernd Leno, was forced to exit the game injured in the first following a clash with Maupay.
As he left the pitch on a stretcher, appearing to have injured his knee, Leno pointed his finger at Maupay.
Another crazy ending! 😲

"At half-time, I went to their manager Mikel Arteta to apologise because I never meant to injure their keeper," Maupay told BT Sport after the game.
"Until the keeper gets the ball, you never know what will happen. I just went to get the ball really. I think it was shoulder against shoulder and when he landed, he twisted his knee.
"It's football, there's contact. I never meant to injury him. I'm sorry. I apologise to their team and to him as well. I wish him a speedy recovery.
"I have been through a bad injury, so I know it's hard."
Arsenal took the lead in the 68th minute through Nicolas Pepe. Lewis Dunk had Brighton level seven minutes later and then, in the fifth minute of injury time, Maupay scored the winner.
The Frenchman thought Arsenal got their just deserts.
"Some of the Arsenal players need to learn humility, maybe, sometimes," he said.
"They were talking a lot in the first half and the second half when they were 1-0 up. They got what they deserved."
Maupay also addressed what happened after the game when speaking to BBC.
"Especially one of them," he added regarding Arsenal players needing to learn some humility.
"I mean he was talking the whole game but was saying really bad things. I don't want to say what he said because I could be in trouble.
"It was in French because he's French. So when I scored I just needed to say, 'Listen, that's what happens when you talk too much on the pitch'."
Matteo Guendouzi was the only French player Arsenal had on the pitch at the final whistle.
"I never meant to hurt Leno."
"Some of the Arsenal players need to learn humility."
"They got what they deserved."
