Full-time: Manchester City 5-0 Liverpool
Stunning from Sane! Liverpool are spent and haven't got the will to close down City as they switch the ball from left to right. Walker receives it and slides a ball in field to Sane who has time and space to turn, move the ball onto his left and bend a wonderful effort into the top corner. Two for him off the bench today.

Alex Oxlade-Chamberlain's Arsenal career ended with a 4-0 defeat and it looks like his Liverpool career is going to begin with one too.
It could be worse. His Gunners debut came in that infamous 8-2 defeat at Old Trafford.
Sane makes it four! Again, De Bruyne is involved, threading a ball down the middle for the German who plays an superb one-two with Mendy, who has raced up alongside him on the left. Sane meets the return pass with a fine first time finish into the far corner.

Mendy does brilliantly out on the left, swerving inside two players before cutting a dangerous ball across goal that Klavan just about manages to clear. Liverpool have just over 15 minutes left to run down here.
Here's another change for City and another man who's just back from South America in Otamendi is off with Eliaquim Mangala onto replace him.
Brilliant from City again who are slicing through Liverpool at the moment. A clever run from Sane down the inside left is picked out and he guides the ball across goal for De Bruyne. For one, the Belgian's technique is off, leaning back and hammering it well over the bar.
City goalkeeper Ederson has not travelled to hospital but is still being assessed by the Etihad for possible fractures to the cheek and jaw.
Another change for Liverpool, James Milner on for Wijnaldum.
There are no signs of Liverpool shutting up shop to try and keep this civilised at the moment. Guardiola meanwhile is going to take the chance to hand a rest to Gabriel Jesus, whose just back from international duty in South America. He doesn't look too pleased mind, as you would expect having scored twice already today. Leroy Sane comes on for him.
This could ugly real quickly for Liverpool. Sergio Aguero breaks free from the Liverpool backline, left one on one with Mignolet but unselfishly knocks it across to Jesus for an easy tap in.

The second half has started almost at a walking pace. It could be a long half for Liverpool.
We are back underway for the second half and Jurgen Klopp has made his first change of the game, with Alex Oxlade-Chamberlain on his for debut. Salah has made way.
Half-time: Manchester City 2-0 Liverpool
This time it counts! It's pretty similar to the one that was ruled out a few minutes ago with De Bruyne, this time out on the left, lifting another perfect cross into the six yard area. Jesus leaps, twisting in the air to firmly plant it past Mignolet to tighten his side's grip on the game.
Goal! Manchester City 2-0 Liverpool (Gabriel Jesus, 45+5)
Eight minutes of time added on, by the way.
Play is back underway and City have the ball in the back of the net! But it won't count. De Bruyne lifts a superb ball in from the right but Jesus is stood in an offside position as he heads past Mignolet.
There's gonna be a lot of added time here, at least six minutes at this rate.
Ederson meanwhile is still down after that challenge and it doesn't look like he will be able to continue. The stretcher is out and Claudio Bravo is about to come on.
