Arsenal arrived at the Amex Stadium on Saturday chasing an eighth straight win to open the season, a feat the club had not managed in 123 years. They left having been beaten 3-0, out-shot 17-11 and comprehensively out-fought by a Brighton side who have now made a habit of dismantling English football’s reigning champions.
Pascal Gross curled in from outside the box on 31 minutes, Charalampos Kostoulas drilled a second from 25 yards in first-half stoppage time, and 21-year-old summer signing Chema Andres headed a corner past David Raya on 57. Mikel Arteta’s team, unbeaten in seven across three competitions, never recovered.
“A very disappointing result and performance,” Arteta said afterwards. Fabian Hurzeler was rather happier: “Beating the current champions is something special.”
Two strikes from distance, one from a corner
The pattern was set inside seven minutes, when Raya had to deny Kostoulas and Brighton’s press repeatedly forced Arsenal backwards. The champions eventually found a footing — Riccardo Calafiori headed wide, Bukayo Saka probed down the right — but the opener came against that run of play and from a distance Arsenal have grown uncomfortable with. Gross, collecting on the edge of the area, bent a right-footed shot in off the post.
Kostoulas doubled it in the final seconds of the half with an almost identical geometry: possession won high, a low drive from 25 yards, Raya beaten at his far post. Seven of Arsenal’s last 18 Premier League goals conceded have now come from outside the 18-yard box.
The third was more prosaic and more damning. Andres, signed in the summer and starting in midfield, rose unmarked from a corner 12 minutes into the second half. Arsenal’s response was a Kai Havertz one-on-one that Bart Verbruggen saved without much difficulty.
The underlying numbers flatter Arsenal, and Arteta will know it does not matter. Brighton had 40.3% possession and generated 1.33 expected goals to Arsenal’s 1.58; they also created four big chances to Arsenal’s two, and took theirs. Brighton have scored 16 goals in five league games, more than any side in their opening five since Manchester City’s 19 in 2022-23.
The champions’ regular tormentor
This is not an anomaly. It is the third consecutive season Brighton have beaten the reigning Premier League champions at the Amex, following wins over Manchester City in 2024-25 and Liverpool in 2025-26. Hurzeler’s side have built an identity around exactly the kind of afternoon Arsenal endured: high turnovers, direct transitions, shots taken early rather than worked into the six-yard box.
For Arsenal, the historical markers are less welcome:
- Their heaviest Premier League defeat since May 2023 — also a 3-0 loss to Brighton
- Their heaviest defeat as defending champions since a 3-0 loss at Everton in October 1989
- The end of a run of seven straight wins, including four from four in the league, a Champions League victory over Napoli and a Carabao Cup win at Ipswich
Individually, Gross scored in three consecutive games for Brighton for the first time in his career across all competitions, a notable line for a player whose best years were assumed to be behind him. Kostoulas, meanwhile, already has six goal involvements this season — double his total for all of 2025-26.
A title race that suddenly has a shape
The defeat costs Arsenal top spot. They sit second on 12 points, behind Manchester City on goal difference, with Brighton third on 11 as the three-week international break arrives. Five games is a small sample, but it is now a table with three credible contenders rather than a procession.
The more useful question for Arteta is whether Saturday exposed something structural. Arsenal’s title defence has been built on control — dominating the ball, conceding little, winning narrowly. Brighton refused them the first of those, and the other two collapsed with it. Sides with pace in transition and confidence to shoot from range will have watched closely.
Arsenal have three weeks to work on it before Leeds United visit the Emirates on 10 October. The break is well timed; so, from Brighton’s perspective, is the timing of a result that will sit in the league table and in Arsenal’s memory until then.

Two notes on sourcing: the manager quotes are short because Sky’s report was only partially retrievable — both fragments are verbatim as far as they go, but you may want to extend them from the full post-match presser. Sources reported goal minutes as either 30/45/56 or 31/45/57; I used the latter, which two independent sources agreed on.
