If City score now it may make the last 20 minutes interesting. And they have a chance! James Milner will a slack backpass, Raheem Sterling is in on goal and squares to Sergio Aguero, he has to get round one defender before testing Simon Mignolet from 18 yards.

Seconds later Fernando stretches to reach a free-kick but can't keep it down.

But Barcelona do have a fourth! Luis Suarez again. Barcelona brought Lionel Messi on at 3-0 up by the way...

Liverpool think they have a fourth as Philippe Coutinho rounds Joe Hart to slot in - but he was a few yards offside...

Joe Hart has a wonder save in every game, that was world class and he keeps Manchester City in this game.

Superb save from Joe Hart! Liverpool inches away from burying this game as again they play Roberto Firmino clean in on goal, he tries to lift it into the net but Joe Hart makes himself big and keeps it out with a hip. Wonderful goalkeeping. 

The second half has not been the best but City now put together a neat move, Kevin de Bruyne has the awareness to slide a pass into the feet of Raheem Sterling. He pauses, takes aim and fires - but it's easily blocked.

Philippe Coutinho is a beautiful and intelligent footballer. He is just like David Silva, being able to find space when on the ball. 

He is growing in that role for Liverpool. That is why Manchester City are missing Silva so much, he brings something different to the table.

Don't do it!

Fabian Delph shoots from, ooh, at least 35 yards. And toes it well wide. Not the answer.

How's your game management Liverpool? Good so far as they sensibly keep the ball when they can and their shape when they can't. Sergio Aguero is whistled for a late one on James Milner. The home fans are not happy.

Emre Can is booked for what I thought was a belting tackle on Fernandinho. City starting the second half at a frantic pace. As they must.

Manuel Pellegrini is being brave. I thought he would change the defenders but let's see how the midfield substitutes change this match for Manchester City.

Under way!

Jesus Navas and Yaya Toure get the half-time hook. On come Fernandinho and Fabian Delph.

A good image from the first half as Martin Skrtel shows Sergio Aguero exactly how the City supporters must have felt going 3-0 down on half an hour.

Another absolute belter of a goal - Andres Iniesta has scored a superb strike from the edge of the penalty area and Barcelona are cruising.

Manchester City's fans were in the mood to give their team a right going over after a shambolic performance - but suddenly that brilliant strike from Sergio Aguero has changed the mood.

It's a long way back for City and Liverpool have been outstanding. Where there is Aguero there is hope but who is to say Liverpool will not score more if City carry on defending like that?

Martyn Jones: What is happening at the Etihad Stadium? Is this the rebirth of Liverpool Football Club?

Dalot65: Sergio Aguero always scores against Liverpool but hey, we have three goals and nobody saw that coming. Klopp's half-time team-talk will calm them!

Rohan Patwardhan: Okay, Sergio Aguero is the right-footed Messi. I am not joking. Just needs to sort fitness issues.

"City have got that speed and flair to be able to break down any team - we've seen flashes of that. But they haven't dealt with Philippe Coutinho at all and there's been several mistakes in defence.

"Sergio Aguero has scored one already and he will be key to this second half. And I also expect to see Nicolas Otamendi come on - because so far there's been no confidence at the back."
