Mikel Arteta did not mince words after Arsenal’s 3-0 defeat to Brighton at the Amex Stadium, openly accusing his own players of failing to "respect the game". The three-goal margin, delivered by Pascal Gross, Charalampos Kostoulas and Chema Andres, marked Arsenal’s heaviest Premier League loss in three years and abruptly halted their early-season winning streak. In his post‑match press conference, Arteta highlighted the physical shortcomings of his side on the south coast, noting that the Gunners were out‑muscled in almost every duel. He also lamented the technical sloppiness that left Arsenal vulnerable to Brighton’s high‑pressing approach.

"A very disappointing result and performance," he said, adding that Brighton deserved full credit for the way they executed their game plan. "They were another gear from us in the basics of the game.

They were always first in the first duel, in the second actions, second balls, and they started to play from there," Arteta explained. He went on to stress that when Arsenal possessed the ball, especially in their own half, they displayed "extremely poor" technique and failed to honour the fundamental principles required when facing a team that presses man‑to‑man. This, he argued, prevents any team from dominating or controlling the match on their own terms. The manager also pointed out that Arsenal squandered several clear‑cut chances, failing to convert them into goals.

"We have to make sure we learn the lesson because this can't happen again," he warned. He elaborated that many moments in the game were 50‑50 battles for possession, and more often than not the ball ended up with Brighton.

Technical errors compounded these issues, opening up Arsenal in dangerous ways that they struggled to rectify. Arteta recalled how, from the very first throw‑in, the tone of the match was evident. "We put ourselves in trouble one time, two times, three times and we needed to get out of that much quicker than that," he said, describing the repeated lapses in concentration as a key lesson for the squad.

The loss snapped Arsenal’s run of eight consecutive Premier League victories. Despite his harsh assessment, Arteta urged patience and perspective as the team heads into a three‑week international break. "It’s not going to take away what the team has done and the boys have done in the last six or seven weeks since coming back from the World Cup," he asserted. He reminded everyone that 18 players have returned from the tournament, and the collective effort over that period has been remarkable, with the side winning a significant number of games.

He concluded that the defeat serves as a stark reminder of the standards required to succeed at the highest level: "But this is a big lesson for all of us to understand what it takes to win at this level." Sky Sports analyst Nick Wright noted that Arsenal rarely get out‑worked, but Brighton’s intensity proved too much. The visitors applied relentless pressure from the outset, a fact underscored by Opta data showing Brighton won possession in the final third nine times – the second‑highest total in a Premier League match this season and the most ever recorded against Arsenal in any game this term or last.

Arsenal appeared disoriented by the early onslaught, with new signing Bruno Guimarães particularly struggling to find his footing. The Gunners never regained composure, allowing Brighton to dominate not only in open play but also from set‑pieces. The third goal came from a well‑executed corner, sealing a comprehensive victory and avenging Brighton’s loss in the same fixture the previous season.

Brighton manager Fabian Hurzeler praised his side’s "special" performance, noting that the win moved his team up to third place, just two points behind Arsenal. Their tally of 16 goals in the first five games is the highest for any Premier League club this season, second only to Manchester City’s 19‑goal start in 2022/23.

"Beating the current champions and the best team in England is something special," Hurzeler said. "But it’s not because the result is special, it’s the performance. The boys showed real togetherness and intensity.

They were horrible to play against because we did the basic things right. Overall I was very pleased with the performance. I think we deserved to win. It’s a moment the players and the staff can enjoy because they worked hard for this, but it’s also important why we had this success – because we did the basics right and we were brilliant in the duels."
