Mikel Arteta did not mince words after Arsenal’s 3-0 defeat to Brighton at the Amex Stadium, lambasting his own players for not "respecting the game" when they were outclassed by the visitors. The loss, which saw Pascal Gross, Charalampos Kostoulas and Andre Chema find the net, marked Arsenal’s heaviest Premier League setback in three years and abruptly halted their unbeaten start to the season. Arteta’s post‑match interview highlighted two main deficiencies: a lack of physical tenacity in the battles down the right‑hand side of the pitch, and a sloppy, indecisive approach on the ball that allowed Brighton’s high‑press to dominate.

"It was a very disappointing result and performance," the manager said, giving credit to Brighton for their disciplined display. "They were a different gear from us in the basics of the game.

They were first in the first duel, in the second actions, second balls, and they built from there." He went on to stress that Arsenal’s technical execution was sub‑par, especially when in possession in their own half. "We were extremely poor technically, not respecting the game and the principles you have to apply against a team that wants to press you man‑to‑man.

That never gives you the option to dominate and control the game in the manner you want. And when we had big chances, we didn’t put them away," Arteta added. The manager warned that such an exhibition could not be repeated.

"We have to make sure we learn the lesson because this can’t happen again," he said, pointing to the numerous 50‑50 moments that swung in Brighton’s favour. He noted that technical errors at crucial junctures opened Arsenal up to dangerous attacks, and that the team repeatedly found itself in trouble, needing to recover quickly each time. The defeat snapped an eight‑match Premier League winning streak for the Gunners.

Despite his criticism, Arteta urged patience and perspective as the squad headed 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 reminded the media. "With 18 players coming back, what we’ve done, the way we’ve competed and the amount of games we’ve won has been remarkable. 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 observed that Arsenal rarely get out‑worked, but Brighton’s intensity proved too much.

The Seagulls applied relentless pressure from the opening whistle, and Arsenal could not match that level in either half. Opta data underscored Brighton’s dominance: they won possession in the final third nine times, the second‑highest total in a Premier League game this season and the most ever recorded against Arsenal this campaign. Arsenal appeared disoriented by the early onslaught, with new signing Bruno Guimarães particularly struggling to find rhythm under the press.

The Gunners never regained composure, and Brighton capitalised on set‑piece opportunities, scoring their third goal from a well‑executed corner. The victory also served as a form of revenge for Brighton, who had suffered a bitter loss to Arsenal 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 by any Premier League club since Manchester City’s 19‑goal start to the 2022/23 season. "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 staff can enjoy because they worked hard for this, but it’s also important to understand why we had this success – we did the basics right and we were brilliant in the duels." For Arsenal, the loss serves as a stark reminder that technical skill alone cannot compensate for a lack of physical commitment and mental sharpness. Arteta’s comments suggest a forthcoming period of introspection, with an emphasis on improving pressing resistance, ball retention under pressure, and finishing efficiency.

As the squad returns from international duty, the challenge will be to translate those lessons into a more resilient display, ensuring that the early season momentum is not lost and that the team can reclaim its status as title contenders.
