Brighton & Hove Albion stunned Premier League champions Arsenal with a commanding 3-0 victory at the Amex Stadium on Saturday, September 19, 2026, bringing the Gunners’ perfect start to the new league campaign to an abrupt end.

Pascal Groß opened the scoring in the 31st minute before Charalampos Kostoulas doubled Brighton’s advantage just before half-time. Chema Andrés then added a third in the 57th minute to complete one of Brighton’s most impressive victories over Arsenal.

For Arsenal manager Mikel Arteta, the defeat was particularly damaging because his side had won their opening four Premier League matches and conceded only once before travelling to the south coast.

Arteta admitted afterwards that Arsenal had been second best in the physical and technical aspects of the contest, saying the team had to learn from what he described as a “big lesson.”

Here are 10 key statistics that tell the story of Brighton’s victory and Arsenal’s first league defeat of the season.

1. Brighton scored three goals from 17 shots

Brighton finished the match with 17 attempts, compared with Arsenal’s 11.

The Seagulls also registered five shots on target, while Arsenal managed only two.

The numbers underline Brighton’s greater threat in front of goal despite Arsenal having more possession.

2. Arsenal had 60% possession — but still lost 3-0

Arsenal controlled 60% of possession, leaving Brighton with 40%.

However, possession did not translate into goals or enough clear attacking opportunities.

Brighton were more direct and effective when they won the ball, while Arsenal struggled to turn their possession into sustained pressure in dangerous areas.

3. Arsenal managed just two shots on target

One of the most striking statistics was Arsenal’s lack of accuracy in attack.

The Gunners produced only two shots on target throughout the match, compared with Brighton’s five.

That statistic helps explain why Arsenal finished the afternoon without scoring despite controlling much of the ball.

4. Brighton won possession in the final third nine times

According to Opta data cited by Sky Sports, Brighton won possession in the final third nine times.

That was the second-highest figure recorded by any team in a Premier League match this season at that point and the highest number achieved against Arsenal during the current campaign or the previous one.

The statistic illustrates how effectively Brighton disrupted Arsenal’s attempts to build from the back.

5. Arsenal’s expected goals figure was 1.58

Despite failing to score, Arsenal recorded an expected-goals figure of approximately 1.58, compared with Brighton’s 1.33.

That suggests Arsenal did create opportunities that, based on the quality of chances, could have produced a goal.

But Brighton were far more clinical with the opportunities they created, while Arsenal failed to convert theirs.

6. Brighton scored twice before half-time

The first half proved decisive.

Groß gave Brighton the lead in the 31st minute before Kostoulas struck again in the 45th minute, sending the hosts into the interval 2-0 ahead.

The second goal came at a particularly damaging moment for Arsenal, leaving Arteta’s team with a significant deficit to overcome after the break.

7. Chema Andrés scored on his first Premier League start

Brighton’s third goal came from Chema Andrés, who was making his first league start.

The midfielder struck in the 57th minute, extending Brighton’s lead to 3-0 and effectively putting the result beyond Arsenal’s reach.

Brighton’s official match report highlighted Andrés’ first league start as part of a memorable 125th-anniversary occasion for the club.

8. Brighton completed the game with 16 successful tackles

The hosts recorded 16 successful tackles, compared with Arsenal’s 13.

Combined with their pressing and ability to win possession high up the pitch, the statistic reflects the intensity Brighton brought to the contest.

Arteta specifically criticised Arsenal’s performance in the physical battle, saying Brighton were ahead in the first duels, second actions and second balls.

9. Arsenal’s passing numbers were better — but Brighton’s pressure mattered

Arsenal completed 418 accurate passes at an 84% accuracy rate, while Brighton completed 256 at 76%.

On the surface, those numbers favour Arsenal.

But Brighton’s strategy was not based on dominating possession. Their objective was to make Arsenal uncomfortable, force mistakes and attack quickly after winning the ball.

That approach was particularly effective during the first half, when Brighton repeatedly disrupted Arsenal’s build-up.

10. Arsenal suffered their biggest Premier League defeat in three years

The 3-0 loss was Arsenal’s heaviest Premier League defeat in three years.

The last time the Gunners lost a Premier League match by three goals was also against Brighton, when the Seagulls won 3-0 at the Emirates on May 14, 2023.

The latest result therefore gave Brighton a remarkable statistical connection with Arsenal’s biggest league defeats in recent seasons.

What the numbers tell us

The statistics paint an interesting picture.

Arsenal had more possession, completed more passes and actually registered the higher expected-goals figure. Yet Brighton won comfortably because they were more effective in the decisive moments.

Brighton’s pressing was arguably the defining feature of the match. Their ability to win the ball high up the pitch prevented Arsenal from establishing the control their possession figures might otherwise suggest.

Brighton’s official report described the performance as one of Fabian Hürzeler’s best since taking charge, highlighting the home side’s pressing, passing, defending and finishing. A record crowd of 31,944 watched Brighton celebrate their 125th anniversary with the victory.

For Arsenal, the defeat represents an early warning in their title defence.

The champions remain on 12 points after five league matches, but Manchester City can move above them with victory in their game in hand.

Arteta’s response was telling: rather than dismissing the result, he acknowledged that Arsenal had been beaten in the basics and said the team must learn from the experience.

“This is a big lesson for all of us to understand what it takes to win at this level,” Arteta said.

For Brighton, meanwhile, the victory provides another statement of their ability to trouble the Premier League’s biggest clubs.

Brighton 3-0 Arsenal was not simply a surprising scoreline. The numbers show how effectively Brighton turned pressing, intensity and clinical finishing into a victory over the reigning champions.
