Mikel Arteta did not mince words after Arsenal’s 3-0 defeat to Brighton at the Amex Stadium, insisting that his squad had shown a lack of respect for the fundamental principles of the game. The visitors, powered by goals from Pascal Gross, Charalampos Kostoulas and Chema Andres, handed the defending champions the most severe Premier League loss they have suffered in three years and abruptly halted the winning streak that had characterised the opening weeks of the season. Arteta’s post‑match analysis highlighted two main deficiencies. First, he argued that Arsenal were out‑muscled in the physical contests that defined the match on the south coast.

Second, he criticised the Gunners for their technical sloppiness, especially when under pressure in their own half. Brighton’s relentless pressing forced Arsenal into a reactive posture, preventing them from imposing their usual rhythm and from controlling the tempo of the game. "A very disappointing result and performance," the manager said, adding that Brighton deserved full credit for the way they executed their game plan.

"They were a gear above us in the basics of football. They won the first duels, the second‑ball battles and built their play from there." He went on to explain that Arsenal’s own possession was riddled with technical errors. "When we had the ball, particularly in our own half, we were extremely poor technically, not respecting the game and the principles you must apply against a team that presses you man‑to‑man. That never gives you the option to dominate and control the match in the way you want.

And when we finally created big chances, we failed to finish them." Arteta stressed the importance of learning from the experience: "We have to make sure we learn the lesson because this can’t happen again." During the press conference, he elaborated on the moments that swung the match in Brighton’s favour. "There are a lot of moments when the ball is 50‑50 and it changes hands, and most of the time it was for them. Sometimes there were technical errors that opened us up in a very difficult way, but that’s something to learn.

From the first throw‑in you could sense it, it was so clear. We put ourselves in trouble one time, two times, three times and we needed to get out of that much quicker than we did. That’s one of the biggest lessons we have to take from the game." The loss snapped Arsenal’s run of eight consecutive Premier League victories.

Despite the criticism, Arteta urged patience and perspective as the team heads into a three‑week international break. "It won’t erase what the team has achieved in the last six or seven weeks since returning from the World Cup," he said. "With 18 players back, the way we’ve competed and the number 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 noted that Arsenal rarely get out‑worked, but this time they could not match Brighton’s intensity. The visitors’ pressing was described as "incredible" in the first half, and Arsenal failed to raise their level in the second period. Opta data revealed that Brighton won possession in the final third nine times – the second‑highest total in a Premier League match this season and the most ever against Arsenal in any game this term or last.

The early pressure from Brighton left the Gunners disoriented, with new signing Bruno Guimarães struggling to find his footing. Arsenal never recovered their composure, and Brighton’s dominance extended to set‑pieces, with their third goal coming from a well‑executed corner.

The victory also served as revenge for Brighton after a contentious defeat to Arsenal in the same fixture last 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 of the campaign is the highest by any Premier League side since Manchester City’s 19‑goal start in the 2022/23 season. "Beating the current champions and the best team in England is something special," Hurzeler said.

"But it’s not just the result that’s special; it’s the performance. The boys showed real togetherness and intensity. They were terrible 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, and it’s important to recognise why we succeeded – we executed the basics correctly and were brilliant in the duels." The match serves as a stark reminder that even top‑flight teams must respect the fundamentals of pressing, ball retention and physical contest. For Arsenal, the defeat offers a chance to reflect on tactical discipline, improve technical execution under pressure, and restore the winning mentality that has defined their season so far.

The upcoming international break provides a valuable window for recovery and strategic adjustments before the league resumes.
