Arsenal came back from a goal down to defeat Chelsea 2-1 in a Premier League clash at the Emirates Stadium on Sunday.
Kai Havertz levelled things for the defending champions after Morgan Rogers’ early goal had put Chelsea’s nose in front.
Martin Odegaard then scored the second as the Gunners continued their unbeaten run in the league just three matches into the new campaign.
Arsenal delivered an emphatic response to Chelsea’s emergence as potential Premier League title contenders with the win ending their rivals’ unbeaten start on Sunday.
Mikel Arteta’s side trailed to Rogers’ second-minute goal in a pulsating London derby at the Emirates Stadium. But the champions showed why they are firm favourites to retain the title with a blistering response to that early setback.
Havertz bagged the equaliser against his former club midway through the first half, and Odegaard netted Arsenal’s winner soon after the interval.
It was a statement of intent from second-placed Arsenal, who have won all three league matches to sit behind leaders Manchester City on goals scored.
The Gunners’ mature display underlined their desire to win the club’s first back-to-back titles since the 1930s.
For Chelsea boss Xabi Alonso, the defeat ended his three-game winning run in all competitions since taking charge at Stamford Bridge in the close season.
Alonso will realise just how much work Chelsea still have to do before they are in a position to end a title drought dating back to 2017.
Chelsea’s shaky defence is prone to costly miscues, while their vaunted attack found it harder to flourish against Arsenal than in their free-scoring wins over Fulham, Luton and Brighton.
Arteta and Alonso have known each other since their days as childhood friends in the Basque region of Spain.
The chaotic matches of their youth on a gravel pitch in the Berio district of San Sebastian would have seemed calm in comparison to the blood and thunder their teams brought to a raucous corner of north London.
Chelsea beat Arsenal in the race to sign Rogers from Aston Villa in the close season after the Gunners refused to match the Blues’ £117 million ($158 million) bid for the England midfielder.
Rogers showed why Chelsea made him the most expensive British player in history, putting the Blues ahead after just 77 seconds.
