David Silva dealt out a flailing arm and was booked just a few minutes ago. This time he is on the receiving end from Cheikhou Kouyate, who catches the Spaniard with his elbow. The West Ham midfielder gets a yellow and Silva requires some treatment.

On comes Matt Jarvis and Kevin Nolan for Carlton Cole and Alex Song.

West Ham frustrate their manager again as Enner Valencia breaks away and has a chance to find Stewart Downing in space on his right, but dwells on the ball allowing a City defender to cut out his pass when it does come. That is the cue for a double change from the away side...

Tom, Colchester: From a City's fan perspective this should've been the way we played all season. Since we lost to Stoke at home I knew it was going to be a rough season.

West Ham are out of their own half, repeat out of their own half. Stewart Downing floats a cross to the back post where Carlton Cole rises highest but heads the ball harmlessly wide. Looks like we are going to see Kevin Nolan and Matt Jarvis soon.

At some point I'm sure that West Ham will get out of their own half. It has to happen. Doesn't it? It is like attack v defence training for City, who go close again as David Silva drives a shot that hits a group of bodies in the box before being cleared.

David Silva goes into the book for a flailing arm that catches Winston Reid near the throat. He goes down clutching his face.

West Ham have not won away from home since 2 December. They have shown nothing here to suggest that is going to change. The City players are finding space at will in the Hammers half. A long period of pressure offers shooting chances for Yaya Toure, Aleksandar Kolarov and Frank Lampard before Sergio Aguero eventually tries one from inside the box that he fluffs, allowing West Ham to clear. It is surely only a matter of time before City score again.

"Earlier we were asking some of our colleagues locally why Manchester City are not challenging for the title and we were told many performances have been more about the individuals than about the collective. But it's funny because today some of the individual performances out there have been simply outstanding."

What a goal this could have been. Sergio Aguero plays a neat pass into Yaya Toure on the edge of the box and then darts into the box to receive the return ball, which Frank Lampard allows to run through his legs. Aguero has sight of goal but out comes Adrian to block. For a moment, Aguero looks like he has hurt himself but after a bit of treatment off the field he returns. Good news for City, terrible news for West Ham.

West ham have gone 4-4-2, as opposed to the 4-5-1 they adopted in the first half. It means Enner Valencia is now up top with Carlton Cole. He has a chance to chase down a ball and potentially get in on goal but is easily muscled out of possession by Eliaquim Mangala.

The second half starts as the first ended, with City on the attack. Jesus Navas looks to cross low to two team-mates on the edge of the box but a West Ham foot slides in to prevent in reaching them and clear.

The Hammers get the second half under way. No changes to either team.

The West Ham players are the first to emerge from the tunnel for the second half. You suspect their ears might still be ringing.

Jono Forwood: To Liam O'Connor (see 45 mins), as a West Ham fan I can't give you an answer as to what's gone wrong this season but I would quite like an explanation as well!

Steve Huish, Surbiton: What a player Sergio Aguero is. Twenty goals and to think he was injured for two months. If Wilfried Bony can get in the groove they could be deadly next season.

Straight after we've wrapped all the action and reaction at the Etihad we'll be heading over to St James' Park for Newcastle v Tottenham and what it promises to be a heated occasion, complete with varying types of protest from the Newcastle fans against owner Mike Ashley. Here is a little insight into what you can expect...

"It's a case of how many Manchester City want to get in the second half really. How much they want to push themselves in the glorious sunshine. The West Ham fans who have made the long trip up here deserve a side that's at least going to be brave, but if they leave themselves open by going forward they may have to take further punishment, as we saw with Sergio Aguero's goal."

Adam Cordery: This game feels like a friendly.

Joseph Murhpy: With the possible exception of Newcastle, West Ham is probably the best team for City to play to renew confidence.

Paul Phillips: I must admit, bar a few defensive hiccups City's ball retention has been top notch. This has been sorely missed in the past.

"Manchester City have been in control and then some. James Collins still can't quite believe he beat his goalkeeper from about 18 yards to put the home side in front. City are in cruise control and West Ham will do well to avoid a beating at the Etihad."
