Arsenal matched Chelsea’s record for Premier League London derbies following their 5-1 win over Crystal Palace at Selhurst Park.
Gabriel Jesus scored twice, with Kai Havertz, Gabriel Martinelli, and Declan Rice adding to the tally, ensuring a strong comeback after their draw with Everton.
The victory means Arsenal are the first team since Chelsea in 2005 to go unbeaten in all Premier League London derbies within a calendar year, securing eight wins and two draws.
This marks the first time Arsenal achieved the feat since 2004.
Arsenal’s win over Crystal Palace brings them to 33 points, narrowing the gap to Premier League leaders Liverpool to three points, though Liverpool has two games in hand.
The Gunners are also just one point behind second-placed Chelsea, who face Everton on Sunday.
