It's the biggest game of the Premier League weekend. The last two Premier League champions go head-to-head at Stamford Bridge.
Chelsea, who lost after being a goal to the good at Wolves in midweek; will be desperate for a win in London to try and keep up somehow with the ever-relentless Manchester City.
City carried on their unbelievable form with a 2-1 win at Watford - to stay top of the Premier League.
There's world-class players all over the pitch... with ridiculous amounts of money being spent on these players over the years!
We'll do our best to try and combine the two squads and make the best possible team.
GK: Ederson (Man City)
Ederson has been a fantastic signing since he joined the champions last summer.
His distribution is perhaps his most impressive attribute, but his actual goalkeeping is still very strong.
Kepa has started his Chelsea career impressively, but Ederson pips the goalkeeper position.
RB: Cesar Azpilicueta (Chelsea)
Kyle Walker is definitely a shout for the right-back spot, but Cesar Azpilicueta is the best in the Premier League.
The Spaniard's consistency over the last few seasons for Chelsea and Spain has been immense.
His defensive ability is something you rarely see in a full-back nowadays; with his ability to help in the attacking third as well.
CB: Aymeric Laporte (Man City)
This man has been superb since signing for Manchester City last summer. It seemed to take him no time to adapt to the Premier League, like you see with numerous players moving from abroad.
Aymeric Laporte has quickly become City's strongest central defender and the man who would be a huge miss if he picked up an injury.
Vincent Kompany, John Stones and Nicolas Otamendi are three defenders not making it into the team - emphasising the strength in-depth these sides have.
CB: Antonio Rudiger (Chelsea)
Antonio Rudiger might seem a controversial shout here. The three City defenders missing from the side (see above) and David Luiz not getting a space.
Rudiger's defensive stability would make him a great choice alongside Laporte.
He's ever improving at the Blues and he remains a huge prospect for the long-term future at Stamford Bridge.
LB: Marcos Alonso (Chelsea)
This may be the hardest decision of the team. It seems borderline-criminal to leave someone like Benjamin Mendy out of the team.
The two best left-backs in the Premier League, for me. Alonso just edges it simply because of the numbers he gets in front of goal.
The modern full-back is often relied on to contribute with assists (Mendy does have plenty of assists) but goals as well.
Alonso has 14 goals for Chelsea in his three seasons at the Bridge; which is an incredible return for a left-back.
His ability to bang in a free-kick and test the 'keeper from almost anywhere on the pitch means he gets the nod.
CM: N'Golo Kante (Chelsea)
This decision was a bit easier. Not even a City fan could deny N'Golo Kante's brilliance.
Fernandinho would beat 99% of players into this role, but the one he hasn't beaten is Kante.
His all-round brilliance makes him a pleasure to watch, week in and week out.
CM: Kevin de Bruyne (Man City)
It's been a torrid start to the 2018/19 season for KDB. He's spent the majority of it out on the sidelines.
His performances last season in Manchester City's greatest ever season, were inspiring.
The fact City have kept their levels up this season, without a player of de Bruyne's ability, is testament to their squad depth.
CAM: David Silva (Man City)
The man who seems to somehow get better with age. City's greatest ever player? It can certainly be argued.
His elegance, vision, dribbling etc. makes him the best playmaker in the Premier League. And he has been for some years now.
Silva has had an excellent start to this season, with Bernardo Silva and his namesake's form making de Bruyne's absence slightly more bearable for City fans.
RW: Raheem Sterling (Man City)
Raheem Sterling has often been criticised for his lack of numbers in front of goal.
That was fair, his finishing wasn't the best - and he was often wasteful in front of the opposition goal.
But you can't say that nowadays. 18 goals last season for the England winger, has been added to by his eight goals in just 12 matches so far this season.
LW: Eden Hazard (Chelsea)
City's attack is pretty special. So it would take a pretty special player to intervene in this combined XI.
He is pretty special. Eden Hazard is arguably the best player in the Premier League.
Hazard's form recently has dipped a bit. But he couldn't keep up his relentless start to the season. He'll get it back. City will be praying it's not this Saturday.
ST: Sergio Aguero (Man City)
The best goalscorer the Premier League has had since Thierry Henry (?). Sergio Aguero is the man.
His numbers are ridiculous for Man City and he is already renowned as a legend in the blue half of Manchester.
The Chelsea defence could be having nightmares if Aguero turns up on Saturday. A menace for any defence on the planet.
