Mikel Arteta did not mince words after Arsenal’s 3-0 loss to Brighton at the Amex Stadium, insisting that his squad had shown a lack of respect for the fundamental principles of football. The defeat, which saw goals from Pascal Gross, Charalampos Kostoulas and Chema Andres, marked Arsenal’s heaviest Premier League setback in three years and abruptly halted their unbeaten run at the start of the campaign. Arteta’s post‑match interview highlighted two main issues: a physical shortfall in the battles along the south coast and a technical sloppiness that left his side vulnerable to Brighton’s relentless pressing. "It was a very disappointing result and performance," the manager said, adding that Brighton deserved full credit for the way they executed their game plan.

He explained that Brighton operated on a higher gear in the basic aspects of the sport. "They were first in the first duel, in the second actions, second balls, and they started to play from there," Arteta observed. The manager also lamented his players’ technical deficiencies, 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," he added. According to Arteta, this failure to respect the game denied Arsenal the chance to dominate or control proceedings.

Even when clear chances emerged, the Gunners were unable to finish them. "We have to make sure we learn the lesson because this can't happen again," he warned. During the press conference, Arteta elaborated on the pattern of 50‑50 battles that often swung in Brighton’s favour.

He noted that technical errors at crucial moments opened up Arsenal to dangerous situations. "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 that," he said, emphasizing the urgency of addressing these lapses.

The loss ended Arsenal’s impressive run of eight consecutive Premier League victories. Despite his criticism, Arteta called for perspective ahead of the upcoming three‑week international break. He reminded everyone that the recent achievements of the team over the past six or seven weeks, following the World Cup, should not be discounted. "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," he asserted.

He concluded that the setback serves as a vital lesson about what is required to win at the highest level. Sky Sports analyst Nick Wright noted that Arsenal are rarely out‑fought, but Brighton’s intensity proved too much. The visitors’ pressing in the first half was described as "incredible," and Arsenal could not match it in the second period either.

Opta data revealed that Brighton won possession in the final third nine times – the second‑highest total for any side in a Premier League match this season and the most ever recorded against Arsenal in either this term or the previous one. Arsenal appeared disoriented by the early barrage of Brighton pressure, with recent signing Bruno Guimarães particularly struggling to find his rhythm. The Gunners never regained their composure, and Brighton capitalised on set‑piece opportunities, scoring their third goal from a dangerous corner.

This victory also served as a form of 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 season is the highest by any Premier League club since Manchester City’s 19‑goal haul at the start of the 2022/23 campaign.

Hurzeler highlighted the collective intensity and togetherness of his players, stating, "Beating the current champions and the best team in England is something special, but it’s not because the result is special, it’s the performance. The boys showed real togetherness and intensity." He added that Brighton’s success was built on mastering the basics: winning duels, executing set‑pieces, and maintaining defensive discipline. "They were horrible to play against and that’s 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," Hurzeler concluded. The match serves as a stark reminder that even top‑flight teams must respect the fundamentals of the game—physical commitment, technical precision, and tactical discipline—especially when facing opponents who excel at pressing and winning second balls. For Arsenal, the challenge now lies in internalising Arteta’s admonitions, correcting the identified shortcomings, and ensuring that such a lapse does not recur as they aim to reclaim their position at the summit of English football.
