Brighton & Hove Albion produced a stunning performance to inflict reigning Premier League champions Arsenal’s first competitive defeat of the season on Saturday, September 19, 2026, at the Amex Stadium. The 3-0 scoreline flattered Arsenal if anything, with Brighton dominating from start to finish on a day that also marked the Seagulls’ 125th anniversary celebrations. Goals from Pascal Groß, Charalampos Kostoulas, and Chema Andrés sealed a famous victory, with Sky Sports’ Sam Blitz at the stadium stating bluntly: “Arsenal have shown nothing. Absolutely nothing”. The result leaves Mikel Arteta’s side still on 12 points from five games, while Brighton climb to 10 points with a statement win.
Brighton set the tone immediately, pressing Arsenal relentlessly and registering three shots before the Gunners managed a single attempt. The breakthrough came from the evergreen Pascal Groß, who continued his remarkable start to the campaign. The 35-year-old German has now been involved in six goals across his last five matches, having scored against Chelsea, netted and provided two assists against Coventry, scored against Manchester United, and now added Arsenal to that list. Brighton doubled their advantage in first-half stoppage time through 19-year-old Charalampos Kostoulas, who rifled home a low drive from outside the area for his third goal in three matches. The second goal arrived just 15 seconds after Bukayo Saka had wasted a golden chance to equalize at the other end, a moment that perfectly encapsulated Arsenal’s afternoon.
The third goal, which arrived in the 56th minute, was perhaps the most embarrassing for Arsenal’s defence. Groß’s corner was delivered to the far post, where Chema Andrés rose above everyone to head home, with the Arsenal defence static and goalkeeper David Raya rooted to his line. Speaking on Soccer Saturday, former Arsenal forward Paul Merson was scathing: “I can’t see Arsenal scoring. At the moment they don’t even look like getting a shot. Bruno was a million miles off it… I don’t care how good you are, if people close you down and make you work, it becomes a leveller”. Sky Sports’ analysis was equally damning: “This is as poor as a 90-minute display I’ve seen from Arsenal in a long time. Mikel Arteta’s reaction to this will surely be one of anger”.
Arsenal’s team news had offered some encouragement before kick-off, with Jurriën Timber making his first start since March and Bruno Guimarães handed his first Premier League start following his summer arrival. However, the absence of Ben White, William Saliba, and Cristhian Mosquera left Arteta’s defensive options stretched, and it showed. Timber and Guimarães were both withdrawn in the 61st minute after poor performances, replaced by Mikel Merino and Martín Zubimendi. Brighton’s lineup, meanwhile, featured Pascal Struijk and Chema Andrés coming in for the suspended Lewis Dunk and Malick Yalcouyé, with the hosts celebrating their 125th anniversary in style. The defeat ends Arsenal’s nine-match winning league run and raises serious questions about their ability to cope with sides willing to press them aggressively, while Brighton’s performance will be remembered as one of the standout results of the early season.
