Well that brings an end to our Premier League coverage for another day. We'll have all the reaction from Stamford Bridge in the coming hours, but until next time it's goodbye.
Full time: Chelsea 0-1 Manchester City
It may only be the final day in September, but how crucial might that result be come the end of the season? City flex their title muscle by beating the champions on their own patch, a win in which they dominated Antonio Conte's side from the outset.
The player of the season so far Kevin de Bruyne got the crucial goal with a quarter of the game remaining but in truth it could have been more for Pep Guardiola's men. Chelsea meanwhile looked every bit a team who failed to reach the heights of last season. Eden Hazard, albeit on his first league start of the season, was desperately poor.
And Andreas Christensen rises highest but can't keep his effort down. Was that Chelsea's last chance?
OFF THE LINE! City almost double their lead and confirm the win as Sterling picks out Jesus, but his volley is headed away at the last by Rudiger.
Ten minutes on the clock and City are coasting towards what would be a seismic win here. Chelsea have not really offered anything since Alvaro Morata was replaced in the first half.
Nicolas Otamendi does brilliantly to cut out a cross which would have surely led to a goal as Batshuayi prowled on the edge of the six-yard box.
GOAL! Chelsea 0-1 Manchester City (Kevin de Bruyne)
The deadlock is finally broken and you can't say it hasn't been coming. Kevin de Bruyne has been a bit quiet in fairness he ends a rampaging run forward with a left-footed strike which arrows past Courtois.
Stunning block from Alonso keeps the scores level. Walker plays an eye-of-the-needle pass to find Sterling whose pulls back tees up Silva but his Spanish counter-part throws himself in front of the ball.
City open up Chelsea again moments later but Jesus's flicks takes the ball away from Silva's path.
Free kick for Chelsea in a central position 30 yards from goal as Fernandinho trips Hazard. Yellow card for the Brazilian. Hazard gets the ball from a short-taken set-piece and he drive is pushed away by Ederson.
A sign of the steps backwards Chelsea have taken since last season. Last term they would have bullied their way through this fixture and come out of it with a narrow win, but there just isn't the same fortitude within them this season you feel. City might not be physically the most imposing side but they're holding their own.
Chelsea's spells of possession have become brief at best with City dictating this game since it resumed. Raheem Sterling has their latest effort on goal but his rising volley balloons over the bar.
Players out for the second half. Conte's men have been waiting for City for some time, with Guardiola choosing to keep his players in for a few extra seconds. Back under way in west London.
Half time: Chelsea 0-0 Manchester City
What promised to be a end-to-end classic has predictably turned into a tactical battle between two master of the art, in Conte and Guardiola. The latter will be the happier of the two having dominated possession and had the better of the chances but clear-cut opportunities have been few and far between.
Fernandinho heads goalwards and Courtois makes a good save to punch the ball clear. Best chance so far.
Bit of a lull in the game since the Morata substitution. Chelsea have adopted a high press - a tactical change instigated by the introduction of the combative Willian - but City continue to dominate possession. The Blues feeding on scraps somewhat.
Alvaro Morata is not happy here and he gestures to the bench that he needs to come off. Big blow for Chelsea inside just 35 minutes; a reflection of playing two games in a week. Michy Batshuayi scored the winner in midweek but it is Willian who is coming on. Interesting move.
David Silva forces Courtois into a good low save as City go again. End-to-end game this and chances aplenty.
A sign of the threat City possess on the break as De Bruyne releases Sterling. Silva and Jesus are free in the box but Sterling overhits the cross and the chance is gone. But a real warning for Chelsea there.
Three times Chelsea go close to taking the lead. Otamendi prevents Morata converting from Rudiger's cross, before Ederson saves from Azpilicueta. Stones then puts behind from the follow-up cross.
Gabriel Jesus almost gave City the lead moments earlier as the visitors' high press forced Courtois into clearing the ball long, and it nearly allowed the Brazilian to benefit but the ball rebounded wide. Big let off for the Blues.
Alvaro Morata breaks the offside trap but the linesman's flag goes up. Neither side have a grip on the game just yet but as we know they could explode into life at any point.
Very fast start this game despite chances being few and far between. Can't see this game ending goalless such is the attack talent on show, and the defensive issues which have been exposed at both ends.
First chance for Chelsea and Alvaro Morata comes close inside three minutes. N'Golo Kante crosses and Morata flicks goalwards but can't find the target.
Players out and we're ready to go. Can Chelsea curb free-scoring City, or will Pep Guardiola claim what would be among the most significant results of his spell in England?
So how about some predictions ahead of the summit meeting? I am going for Chelsea 2-1 Manchester City
Include your predictions below.....
A big afternoon for the fit against Eden Hazard, who starts a Premier League game for the first time this season. The Belgian was at his very best at Atletico Madrid but the one question over him has been his performances on a consistent basis in big games.
Can he silence the doubters?
So the 3pm kick-offs are over and now we can turn our full attention to the main game of the day as Chelsea, the title holders, host Man City, the title favourites. This is the biggest match of the season so far and could go a long way to determining who is crowned as champions come next May.
We're entering the dying embers of the 3pm kick-offs in the Premier League. Head this way to follow the final minutes of those five matches.
Two changes for Chelsea as Antonio Rudiger and Andreas Christensen come in for Victor Moses and the suspended David Luiz.
City make one change which is enforced due to Sergio Aguero's car accident, with Raheem Sterling coming in. Fabian Delph starts a second game in a row.
How will City cover for the loss of Sergio Aguero this afternoon? Jesus Navas, Kevin de Bruyne and David Silva are shoe-ins, but who of Leroy Sane and Raheem Sterling will complete that line-up? Options galore for Pep Guardiola.
Before we focus on the game, there was a positive update regarding Sergio Aguero's condition overnight. He is expected to miss between two and four weeks for City.
Team news on the way from Stamford Bridge, but how might both sides line-up?
David Luiz is suspended and will be replaced by Andreas Christensen. Antonio Rudiger could replace Gary Cahill. Eden Hazard is likely to make his first league start of the season.
City are without Sergio Aguero after he was involved in a car crash on Thursday. Benjamin Mendy will miss much of the campaign after knee surgery, while Vincent Kompany remains out with a calf problem.
Seven games into the season and we have our first stand-out game of the campaign as the title holders welcome the title favourites. Chelsea have started the term slowly but are in full gear now and proved against Atletico Madrid they are a match for anyone on the continent.
City meanwhile have been plundering goals but arrive in west London without striker Sergio Aguero after he was involved in a car accident, while Benjamin Mendy is out for much of the rest of the season with a knee injury. Nevertheless, the Premier League's highest scorers will be keen to flex their credentials to win the championship this evening.
All the team news and build-up ahead of the 5:30pm kick-off on the way.
