Arsenal's perfect start to the Premier League season came to an end as they suffered a 3-0 defeat to Brighton at the Amex Stadium. The loss, their first of the campaign, marked a significant setback for the defending champions, who had entered the weekend tied with Manchester City at the top of the table.

Brighton dominated the match from the outset, exposing weaknesses in Arsenal's usually solid defense. Goals from Pascal Gross and Charalampos Kostoulas before halftime, along with a third goal in the second half, left the Gunners reeling. Manager Mikel Arteta acknowledged the defeat as a "big lesson," emphasizing the need for improvement.

Defender Ezri Konsa admitted there were "no excuses" for the poor performance, calling on the team to "learn and fix" their issues. The result has sparked concerns about Arsenal's title ambitions, with some analysts warning of a potential challenge from rivals like Manchester City.

The defeat has also drawn attention to the team's lack of consistency, raising questions about their ability to maintain their position at the top of the league. As the season progresses, Arsenal will need to address these issues quickly if they are to retain their Premier League crown.
