Man City 1-3 Chelsea: Antonio Conte's men lay down title marker

Chelsea laid down a huge marker for the Premier League title by coming from behind to beat Manchester City 3-1 in a game that boiled over on Saturday at the Etihad Stadium.

City took the lead on the stroke of half-time courtesy of a Gary Cahill own goal before second-half strikes from Diego Costa and Willian swung the game in Chelsea's favour.

Costa's equaliser on 60 minutes came after a period of relentless City pressure during which Kevin De Bruyne missed a glorious chance from just four yards out.

Eden Hazard wrapped up the points in injury time to stretch Chelsea's winning run to eight games in the league but that was not the end of the drama as Sergio Aguero was dismissed for an ugly tackle on David Luiz before Fernandino followed him down the tunnel for an altercation with Cesc Fabregas.

The victory moves Chelsea four points clear at the top of the Premier League while City, who were four points clear themselves at the end of September, have now taken just 12 points from their last eight games. 

Much was made of the tactical battle between the two managers in the build-up and Pep Guardiola decided to match Conte's 3-4-3 formation.

Guardiola made six changes from the team that beat Burnley 2-1 last weekend with David Silva and De Bruyne back in the starting line-up. Raheem Sterling, Yaya Toure, Nolito, Fernando, Gael Clichy and Bacary Sagna were the six players to drop out.

It was just the single change for Conte, who lost Nemanja Matic to a "small muscular problem" with Fabregas replacing him.

Despite City starting with good intent, it was Hazard who had the first shot when curling an effort from 20 yards inches wide of the post after 15 minutes.

Aguero tested Thibaut Courtois from a similar distance 10 minutes later but the goalkeeper helped it on its way over the crossbar.

City did have the ball in the net moments later but Fernandinho's header from close range was ruled out as he was a yard offside from De Bruyne's set-piece.

Luiz was thrust into the spotlight on 30 minutes as he obstructed Aguero as he attempted to latch onto a poor back-pass by Cesar Azpilicueta.

It seemed like referee Anthony Taylor was about to blow for the free-kick - and potentially a red card for Luiz as the last man - but ended up waving play on, much to the annoyance of the home fans.

Those boos turned to cheers just before half-time though as City took the lead. Jesus Navas swung a hopeful ball into the near post and Cahill awkwardly swung a right foot at the ball which deflected into the top corner.

The goal visibly shook Chelsea but City were unable to take advantage of their defensive frailties

De Bruyne snuck in behind but was denied at the near post by Courtois before Cahill and Marcus Alonso got into bother on the edge of their box but Aguero's effort was cleared off the line by the former.

De Bruyne should have doubled City's lead on 57 minutes after they opened up Chelsea down the right flank. Ilkay Gundogan rolled the ball across for the Belgian but with the goal gaping he could only hit the crossbar

And the miss would prove to be costly as Chelsea found their stride and were level three minutes later, Costa bringing down a Fabregas ball over the top, before beating Nicolas Otamendi and firing low into the net from 15 yards.

The game was now end-to-end and it was Chelsea that showed a more lethal instinct with Costa the architect. He bruised his way past a timid Otamendi tackle in midfield and released substitute Willian, who shot low into the corner (70).

City had little response and it was left to Hazard to dance away past Alexander Kolarov in injury time to seal the points.

With the clock running down, the game ended on a sour note as Aguero launched into a reckless high tackle on Luiz by the touchline, both benches getting involved in the melee that followed. 

The red card was brandished to Aguero and also Fernandinho, who appeared to grab Fabregas by the throat as City lost their cool as well as the game.
