The real reason Arsenal couldn't handle Brighton

Arsenal lost 3-0 against Brighton, breaking their unbeaten run so far in the Premier League season, and losing a game by more than 2 goals since the United loss in January at the Emirates last season. And also haven't lost 3-0 since May 2023, ironically, to the same opposition. This current Arsenal side usually loses narrowly, never by outright domination, yet Brighton changed that on Saturday.

Brighton were simply superior. Arsenal’s identity as an elite off-ball, possession-based, and controlled side was dismantled completely by their opposition.

Arsenal struggled to establish any passing rhythm. Raya, Konsa, Gabriel and Calafiori were forced into rushed decisions, and Brighton’s pressing stopped Rice and Guimarães from receiving possession. This led to a game of long balls, forced errors, and a lack of control from Arsenal.

Opta data highlighted a key issue. Seven of the last 18 Premier League goals Arsenal have conceded have come from outside the 18-yard box, which also includes the two Brighton goals. Gross and Kostoulas had punished Arsenal in this sense; however, positional mistakes were an issue too. Calafiori, who has been one of Arsenal’s biggest threats due to his inverted patterns, was effectively marked by Diego Gomez. This became one of the reasons that hindered Arsenal’s ball progression on that side. In addition, his failure, alongside Gabriel, to track Gross and being caught out of position for Kostoulas’ strike.

The midfield struggled under pressure, and the attack lacked the pace to threaten Brighton in transition. Arsenal did not have a profile that was able to stretch the game. This is where the absence of Martinelli is missed. Irrespective of the grand opinion on Martinelli and whether he is good enough for Arsenal, a positive attribute that Arsenal did not reinvest in is his ability to use his pace in a breakaway. Tzolis offered flashes, but the breakaway where he was chased down exemplified this absence.

It can also be suggested that Arsenal may benefitted from the substitution of Madueke in this instance, particularly where added pace and directness out wide were urgently needed.

Brighton’s plan

Speaking to TalkSport, Hürzeler described his methods as “old school…win the first header, the first tackle, the first throw-in, the first corner.” This was also supported by Arteta, who implied that he had a feeling of the game's outcome: “From the first throw-in you could sense it, it was so clear.”

Albeit, all credit to Brighton. They were superior in every metric; understood their roles, and were consistent from minute one to the final whistle. A statistic from Opta Analyst stated that Brighton have beaten the reigning champions three times: (Arsenal 26/27), Manchester City in 2024-25 and Liverpool in 2025-26. It illustrates Brighton as a formidable side, and capable of unsettling the best teams.

Will this happen again to Arsenal?

It is unlikely. The loss was due to a few factors, but mostly tactical superiority, forcing errors, and winning the physical battles. Brighton’s perfection led to a perfect win.

Arsenal will live and learn. It is a two-week break from Premier League football and a chance to reset. But as they face Leeds after the international break, they must learn from their mistakes, as the Emirates awaits the Whites on 10th October.
