Brighton beat Arsenal 3-0 at the Amex Stadium on Saturday, handing the defending Premier League champions their first league defeat of the season and letting Manchester City take over at the top without kicking a ball.
Two goals before the break
Brighton were the better side from the start and went in at half time two goals up, both from strikes outside the penalty area. Arsenal had arrived unbeaten, but they could not live with Brighton's pressing, and the home side's angles and movement repeatedly put runners into space behind the visiting midfield. A third goal after the interval ended the contest. The win took Brighton to 10 points from five matches and left Arsenal level on 12 points with Manchester City, behind on goal difference.
Arsenal's warning signs
Arsenal had conceded only one league goal in their first four games, the best defensive record in the division, so the clean sheet record and the manner of the defeat are both new information for their coaching staff. Injuries in defence have forced changes at the back, and Saturday suggested the replacements are not yet settled. For Brighton, whose home form has been strong, the result is a marker against a title contender.
City and the title race
Manchester City now sit top, and the gap between the top two is goal difference rather than points. Early season tables rarely settle anything, but the shape of the race is already clear: Arsenal and City look like the strongest teams again, and a single bad afternoon changes the order. Brighton's result also adds them to the group of sides capable of taking points off the leaders, which is how a title race tightens without anyone noticing. Arsenal's next fixtures will show whether Saturday was an off day or a warning.
