Martin Odegaard scored his first Premier League goal of the season as Arsenal survived a nervy finale to beat Brighton and return to the top of the table.
The Gunners, who had dropped to second place after Manchester City beat Nottingham Forest in Saturday's early match, took the lead when Bart Verbruggen's goal-kick was intercepted and Bukayo Saka teed up captain Odegaard to score from the edge of the area.
