Here he is!

And what a chance for Chelsea. Romelu Lukaku shrugs off John Stones, drives towards the box and tries to slip in Hakim Ziyech.

It's inches past Ziyech but he was offside anyway. Lukaku should have had a shot!

The problem so far has been getting the ball to Romelu Lukaku! He's not had a sniff yet.

Because of the amount of minutes played by Ruben Dias recently, I think Romelu Lukaku would have been expecting a proper physical battle - I think he'll be licking his lips coming up against John Stones.

They're two players that know each other from Everton. Stones will have to be clever in that battle.

Kevin de Bruyne lifts it in towards Joao Cancelo. Malang Sarr heads it away but it's straight back with Kyle Walker.

Chelsea haven't had the ball yet. They are playing a pretty high defensive line too.

City are able to make runs in behind. Raheem Sterling gets past Marcos Alonso now and wins a free-kick. Alonso is booked for it.

Chelsea manager Thomas Tuchel never takes long to show when he is unhappy and he has just had a spectacular outburst on the touchline about something his team are doing - or not doing.

Two of the game's truly elite managers in opposition today in Tuchel and Pep Guardiola.

Ogabs: I see Pep Deploying same tactics he used against Man United - the wingers will play wide and won't drift in. The runs of De Bruyne and Bernardo need to be picked out by Chelsea.

Aymeric Laporte lifts one over the top for Jack Grealish. Kepa comes charging out to clear it, slices it straight at Cesar Azpilicueta and it ricochets dangerously out for a corner.

From the set-piece, Kepa calmly gathers it in.

Roonie: I’m backing Chelsea to win simply because of N'Golo Kante. The man shows up in big games and is a game-changer.

Kevin de Bruyne picks it up in the middle and Jack Grealish immediately looks to run in behind.

KDB uses the outside of his boot but Cesar Azpilicueta cuts it out. Crucial, because Grealish would have been in.

City have the ball straight off. Raheem Sterling is given one to chase down the right. He turns back inside, pokes it to Bernardo Silva and he hurries a flick back to Kyle Walker to retain possession.

Off we go!

Here come the teams!

In two hours' time, Manchester City could be as much as 13 points clear at the top...

What can Chelsea do to stop that?

Saidmadrid: Tuchel will need to provide all his tactical expertise to try and beat City at the Etihad. It won't be easy but they did it before, so why not this time again?

It's a surprise that Ruben Dias is on the bench - if he isn't carrying a knock. He'd be able to have a good physical competition with Romelu Lukaku and he'd be able to handle that no problem.

More from Thomas Tuchel to BT Sport: "We pushed [Thiago Silva]. He's rushed back. This is the situation in the moment. There will be a lot for him and for N'Golo Kante. We are missing defenders and key players to give us alternatives.

"It is not that I do not have trust in my players. We are strong but we rush things a little bit. We have some ideas but we need a lot of confidence and we need to be aware of the momentum. We will suffer but we need to stick together and it is all about the commitment in the end."

If it's a contest of who's got the most strength in depth on the bench, then Chelsea have already won that. An extremely strong list of substitutes.

Chelsea manager Thomas Tuchel to BT Sport: "Even if we had everybody available and you come to the Etihad it can never be a must-win game. If it is a knockout game then it is different. You have to respect what Manchester City is at the moment. Let's be realistic about us.

"When we are up for a game, we are up for a game. We are up for finding solutions to beat them. It will of course be very difficult. There is a lot to do. This is how we prepare."
