Arsenal’s perfect start to the 2026-27 Premier League season ended emphatically as Brighton & Hove Albion produced a commanding 3-0 victory at the Amex Stadium, with Pascal Gross, Charalampos Kostoulas and Chema Andrés all scoring in a dominant display.

The drama extended off the pitch as well. During BBC Radio 5 Live’s coverage, commentator Ian Dennis paused the broadcast to deliver an on-air apology after inappropriate language was picked up on an effects microphone. “Apologies for any inappropriate language that you may have heard, that might have been picked up from our effects mic here on BBC Radio 5 Live,” Dennis said, in a rare moment of live broadcast controversy during a match that had already shocked the footballing world.

On the field, Brighton’s intensity and organisation left Arsenal with few answers. Alan Shearer, speaking on BBC Radio 5 Live and later on Match of the Day, said the Seagulls “absolutely battered” the champions and could have scored “six or seven” given the quality and volume of their chances. He praised Brighton’s fitness, pressing and collective discipline, noting that every player executed the game plan effectively.

For Arsenal, the defeat ended a seven-match winning run across all competitions and their nine-match unbeaten league streak dating back to April. Mikel Arteta described the result as a “big lesson” for his squad, acknowledging that Brighton were superior in most duels and that technical mistakes in Arsenal’s build-up created dangerous opportunities for the hosts.
