**Chelsea suffered their first Premier League defeat of the season as Arsenal came from behind to win 2-1 at the Emirates Stadium.**
Morgan Rogers gave Xabi Alonso’s side a perfect start after only 77 seconds, but Kai Havertz equalised midway through the first half before Martin Ødegaard completed the turnaround shortly after the restart.
Here are our Chelsea player ratings from north London.
Had an eventful return to the Emirates and needed treatment after an early collision with Gabriel.
Martinez made several important interventions as Arsenal increasingly took control, but he was beaten twice. There was little he could realistically do about Ødegaard’s close-range winner.
Given a huge assignment after coming into the starting XI and largely handled himself well.
Arsenal regularly attacked the spaces around Chelsea’s back three, but Acheampong showed composure beyond his years and did not look overwhelmed by the occasion.
An encouraging performance despite the result.
Had some strong defensive moments but Chelsea’s central defence was stretched too often once Arsenal settled into the game.
The home side repeatedly found routes into dangerous areas and Lacroix could not provide the control Chelsea needed at the back.
Probably the steadiest member of the back three.
Defended aggressively when Arsenal threatened in transition and dealt with several difficult situations, although Chelsea still allowed nine efforts on target across the afternoon.
One of Chelsea’s brighter attacking outlets.
Neto came agonisingly close to restoring the lead shortly before half-time when his low effort struck the post.
Continued carrying a threat down the flank, but the Blues struggled to get him into dangerous situations consistently enough.
The captain started alongside Romeo Lavia in the midfield solution Alonso selected following Moises Caicedo’s absence.
There were good moments on the ball and James contributed to Chelsea’s excellent opening, but Arsenal eventually gained too much control centrally.
It was not a disaster for the midfield experiment, although this was a reminder of just how demanding the role becomes against elite opposition.
A difficult afternoon.
Lavia had to deal with Arsenal’s movement and intensity without Caicedo alongside him, and Chelsea increasingly struggled to retain control through the middle.
Alonso withdrew him for Malo Gusto after 60 minutes.
Played his part in the build-up to Rogers’ rapid opener and provided energy down the left.
However, Arsenal began exploiting spaces more effectively as the game progressed and Alonso replaced him alongside Lavia on the hour.
A surprisingly quiet afternoon by his standards.
Palmer showed flashes when Chelsea improved later in the game, but Arsenal largely prevented him from becoming the dominant creative influence Alonso needed.
Chelsea’s No.10 remains one goal short of another major Premier League milestone.
**Chelsea’s best player.**
Rogers needed barely a minute to make his mark at the Emirates, sweeping home the opening goal and immediately putting his former suitors under pressure.
He continued providing Chelsea’s biggest transition threat and looked capable of making something happen whenever he received possession facing Arsenal’s defence.
The result will frustrate him, but this was another encouraging performance following his £117m summer arrival.
Worked hard at the top of the attack but never managed to seriously impose himself on Arsenal’s centre-backs.
Booked during the first half and largely starved of the quality service he enjoyed during Chelsea’s opening two league games.
Chelsea needed more from their centre-forward once Arsenal moved ahead.
**On for Lavia, 60 minutes.**
Added energy and helped Chelsea become more adventurous after Arsenal had taken the lead.
**On for Hato, 60 minutes.**
A positive cameo without producing the final ball Chelsea needed.
**On for Neto, 81 minutes.**
Almost produced the moment of the match for Chelsea.
The Brazilian cut inside late on and sent a curling effort towards the top corner, only for David Raya to produce an outstanding fingertip save.
He made an impact almost immediately and gave Alonso something to consider ahead of the next game.
**On for Rogers, 87 minutes.**
Not enough time to earn a rating.
Chelsea ultimately created too little for long periods despite threatening late on.
Arsenal held 55% possession and produced nine shots on target compared with Chelsea’s five, while the home side’s greater midfield control eventually told.
Rogers was the standout in blue, while Estêvão’s late cameo was another positive to take from an otherwise frustrating evening.
