Reigning champions Arsenal came from behind to beat big-spending Chelsea in a pulsating London derby at Emirates Stadium.

Chelsea stunned the home fans by taking a second-minute lead through £117m summer signing Morgan Rogers' volley after the Gunners failed to clear Reece James' free-kick.

That was the first goal Mikel Arteta's side have conceded this season.

Despite their flying start, Chelsea had not kept a clean sheet in their previous 18 Premier League games and Xabi Alonso's side were forced to withstand wave after wave of Arsenal pressure.

Emiliano Martinez denied Bukayo Saka, while Jorrel Hato and Wesley Fofana each made crucial blocks before the Gunners levelled in the 25th-minute after former Chelsea forward Kai Havertz beat Martinez at his near post with a well-placed finish.

In a high-quality match, Chelsea - who spent close to £350m in the summer transfer window - came within a whisker of retaking the lead.

After captain James had forced David Raya into a save from outside the box, Pedro Neto hit the post after a wonderful solo run before Martin Odegaard settled it in the 50th minute.

The Arsenal captain beat Martinez after Havertz's clever dummy, the Norwegian's second goal in three Premier League games.

Chelsea substitute Estevao thought he had equalised right at the end of the game but Raya produced a brilliant finger-tip save as the Blues lost for the fifth straight league game at Emirates Stadium.

Good morning Mark, or should I say good evening to our friends in Australia who have already broken the back of the first working day of the week.

Whatever time zone you are in, stick with us as we pick through Sunday's main talking points, starting with Arsenal's metronomic start to their Premier League title defence.

Everton and Manchester United fans, don't worry, we will get to you shortly...

Everton's late comeback at home to Manchester United gave Sunday's second game quite a bit to live up to...and it did not disappoint.

Reigning champions Arsenal were given an early scare by an in-form Chelsea front line.

Chelsea's Morgan Rogers, a summer target for the Gunners, showed them what could have been with his second-minute opener, but Mikel Arteta's side battled back at Emirates Stadium to secure their third Premier League win of the season...

From a surprise deadline-day move to Everton hero, Ainsley Maitland-Niles could not have dreamt of a better way to mark his return to English football.

The former Arsenal full-back started on the bench in his first match for the Toffees since completing a £3m switch from Lyon, but came on with 13 minutes to play and ended up scoring a stunning stoppage-time equaliser as a resilient Everton twice came from behind to draw at home to Manchester United in the Premier League.

They would have to go some to beat Ainsley Maitland-Niles' stunning equaliser for Everton against Manchester United...

Here's the proof.

Manchester City and Arsenal are locked together on nine points and the same goal difference.

City are top on the strength of goals scored - seven to Arsenal's six.

Both sides had to work hard for their third wins of the fledgling campaign.

The Gunners came from behind to win 2-1 at home to previously unbeaten Chelsea on Sunday after Erling Haaland's goal proved enough - just - to beat promoted Coventry at Etihad Stadium.

We are three rounds into the Premier League season and the table has a very familiar look, barring a handful of exceptions.

Results over the weekend mean that we have just two teams left with a 100% record.

Yes, you don't need me to tell you that perennial challengers Arsenal and Manchester City are once again going toe-to-toe at the top of the table.

But spare a mention for Hull City. The promoted side are in third place, unbeaten after three games following Saturday's goalless draw at home to Europa League champions Aston Villa.

Down at the bottom, struggling Villa and Tottenham claimed their first points, although Spurs' goalless draw at Nottingham Forest was not without its controversy.

And Fulham and Coventry prop up the top flight as the only two sides yet to get off the mark.
