Brighton 3-0 Arsenal was a sharp interruption to the Gunners’ winning start to the 2026/27 Premier League season. At the Amex on Saturday 19 September, goals from Pascal Gross, Charalampos Kostoulas and Chema Andres gave Brighton a deserved victory. For Arsenal supporters looking beyond the score, the useful questions concern space outside the penalty area, defending corners and turning promising breaks into clear chances.

Brighton 3-0 Arsenal: who scored?

• 31 minutes: Pascal Gross. A strike from outside the box went in off the post.
• 45 minutes: Charalampos Kostoulas. Another long-range finish put Brighton two ahead before the interval.
• 57 minutes: Chema Andres. A header from a Gross corner completed the scoring.

The result ended Arsenal’s run of four league wins at the start of their title defence. It was also the end of a seven-match winning sequence across competitions, according to the club’s match report. Keeping those two records separate matters: the league run was four games, rather than seven.

Why did Arsenal struggle at Brighton?

Too much room in front of the defence

Brighton’s first two goals came from outside the area. The common question for Arsenal is how quickly the ball-carrier was challenged before shooting. David Raya had already saved an early Kostoulas effort, so the warning arrived well before the opener. Our reading is that reviewing the space in front of the back line will be more useful than treating each finish as an isolated goalkeeping moment.

A corner made the recovery harder

Andres’ header changed the second-half task from chasing a two-goal deficit to needing three just to draw. Brighton also threatened through Pascal Struijk from another set piece. For supporters revisiting the highlights, watch the delivery, the first movement towards the ball and the space at the far post. Those details explain more than a general complaint about intensity.

The few openings needed a better finish

Bukayo Saka had an early attempt blocked and a later effort gathered by Bart Verbruggen. After the break, substitute Viktor Gyokeres found Kai Havertz behind the defence, but the goalkeeper saved the one-on-one chance. Arsenal did find routes towards goal; they did not turn those moments into a foothold in the match.

What should Arsenal fans take from the result?

One defeat does not answer every question about a season, but a three-goal loss deserves more than a shrug. The next useful signs are whether Arsenal reduce shooting space, deal more convincingly with corners and create chances that do not depend on one forward escaping pressure. These are points to watch, rather than claims about changes the coaching staff have already made.
