Arsenal's Premier League restart went from bad to worse on Saturday as they slipped to a 2-1 defeat at Brighton.
The Gunners were swept aside at Manchester City in midweek, but it was a 95th minute goal from Neal Maupay which ensured back to back defeats for Mikel Arteta.
The visitors were the better side in the opening exchanges, with Bukayo Saka crashing a fierce effort off the bar, and Alexandre Lacazette’s diving header forcing a brilliant stop from Seagulls goalkeeper Mat Ryan.
But despite a positive start on the South Coast, Arsenal’s injury curse reared its ugly head again as keeper Bernd Leno was stretchered off just before the break.
Brighton did come into the game after the break with Maupay testing Leno’s replacement Emiliano Martinez, but it was Arsenal who eventually broke the deadlock.
Nicolas Pepe netted a brilliant opener for the Gunners, with the Ivorian – who hasn’t yet shown the extent of his capabilities in the Premier League – bending a superb effort into the top corner.
Brighton aren’t out of the relegation mire just yet, and Graham Potter’s men showed their grit to stay in the game.
Skipper Lewis Dunk scrambled home from close range to draw the Seagulls level with 15 to go, despite Rob Holding’s best efforts to repel him.
With the Gunners simply flat out in added time, Maupay inflicted the game’s killer blow, and perhaps with it Arsenal’s hopes of Champions League football.
The Frenchman raced onto Aaron Connolly’s flick into the penalty area and lifted a fine first-time finish beyond Martinez to secure Brighton a crucial late winner.
