Brighton & Hove Albion ended Arsenal's perfect start to the Premier League season with a 3-0 victory on Saturday, handing the reigning champions their first league defeat of the campaign.

Pascal Gross opened the scoring before Charalampos Kostoulas and Chema Andres added second-half goals to complete a significant result for Brighton on 19 September.

Brighton punish Arsenal

Arsenal arrived having won their opening four Premier League matches, but Brighton disrupted that run with a disciplined performance and three unanswered goals.

Gross gave the hosts the breakthrough in the first half. Brighton then strengthened their position after the interval, with Kostoulas and Andres finding the net to turn a competitive contest into an emphatic 3-0 result.

The final whistle confirmed Arsenal's first dropped points of the league season and gave Brighton one of the standout results of the weekend.

Arsenal's perfect league start ends

The defeat is notable because Arsenal entered the fixture as reigning Premier League champions and had opened their title defence with four successive victories.

A first loss does not define a campaign, particularly this early in the season, but the result interrupts the momentum built during Arsenal's opening run. Attention will now turn to how Mikel Arteta's side respond in their next fixtures.

For Brighton, the three-goal margin provides both points and confidence. Beating the defending champions without conceding represents a major early-season result.

Who scored for Brighton?

The goals came from three different Brighton players:

  • Pascal Gross opened the scoring.
  • Charalampos Kostoulas extended Brighton's advantage after the break.
  • Chema Andres added the third to complete the 3-0 victory.

The spread of scorers underlined Brighton's effectiveness across the match rather than relying on a single decisive moment.

What the result means

The immediate consequence is the end of Arsenal's 100 per cent Premier League record. After four wins from four, the champions leave Brighton with their first defeat and their first significant setback of the new domestic campaign.

Brighton, meanwhile, can use the result as an early benchmark. Taking three points from the defending champions is valuable in itself, while the clean sheet and three-goal return make the performance particularly encouraging.

Key takeaways

  • Brighton defeated Arsenal 3-0 on 19 September 2026.
  • Pascal Gross, Charalampos Kostoulas and Chema Andres scored for Brighton.
  • The result ended Arsenal's perfect four-match start to the Premier League season.
  • Arsenal suffered their first league defeat of their title defence.
