Brighton & Hove Albion won at Arsenal for the first time ever as goals by Adam Webster and Neal Maupay sunk caretaker Gunners manager Freddie Ljungberg's side 2-1 in the Premier League on Thursday.
Brighton's first-half pressure paid off in the 36th minute when centre back Webster pounced on the ball as it came loose after a corner, poking home past Bernd Leno to give the visitors the lead.
Arsenal's Alexandre Lacazette equalised five minutes into the second half with a high looping header from a Mesut Ozil corner which bounced in off the far post.
The home side briefly thought they had taken the lead when David Luiz shanked the ball home from a free kick, only for the Brazilian to be found clearly offside by VAR.
Instead, Brighton's Maupay headed a cross from Aaron Mooy into the far corner past Leno in the 80th minute to give manager Graham Potter's side a historic win in north London.
Arsenal now sit 10th in the table on 19 points, with Brighton a single point behind and three places below them in 13th.
