Kevin de Bruyne pierces the home defence but his pass has too much fizz for Raheem Sterling who takes a heavy touch.

Sam Byram - on his West Ham debut - has cramp. Welcome to the Premier League chief. He can barely even hobble off.

Yaya Toure into the book for a late tackle. Is there any drama to be had late on? Mark Noble again crosses for Nikica Jelavic but Nicolas Otamendi rises to head away. Joe Hart was bouncing nervously on his line there.

Three added minutes. Remember, West Ham have lost just once in 10 outings.

Mark Noble finds a crossing position. The guy has covered every blade of grass. In comes the ball, low, Nikica Jelavic will attack it but gets beaten to the bounce... corner. What a finish, what a day in the Premier League.

In comes the whipped ball, Jelavic again... can't turn it on goal and it's hacked clear.

Match of the Day tonight deserves your attention. Some day.

It's now the away side with energy as Enner Valencia departs with a forlorn look on his face. He's scored two, he could look a little more enthused.

Yaya Toure just blasted a shot which took a full body to block. It would have felled an elephant. Proper power.

“It is very unfortunate. It has come from a challenge and the ball bobbles out and just feeds it straight into the path of Aguero.

“It has not come through good play it has come through some very fortunate circumstances. It is unjust.”

Bingo for Manchester City and credit must go to Kelechi Iheanacho who fresh from the bench, makes a right nuisance of himself in the box.

The result is a bouncing ball for Sergio Aguero, middle of the box, 10 yards out. You know what happens from there.

As the ball nestles in the bottom corner he is angered at the fact he can't retrieve the ball to race back to the halfway line. City are back, just when they looked a little drained.

"The one thing I say about Man City is they have not been at it. They don’t look like this killer outfit at the minute."

Raheem Sterling inside the area, left side, he'll try to forge crossing space and does... LOW ACROSS THE SIX-YARD BOX.... well held Adrian. Brave to dive low where the boots are flying in.

Liz Tray: City's creative 3 - KDB, Toure, Silva - just haven't performed today at all. Not a single chance created of note. 

A look at West Ham's average positions shows us how close together the midfield three of Mark Noble (16), Alex Song (4) and Cheikhou Kouyate (8) have played.

It's disrupted their visitors for sure. You can also see how Aaron Cresswell (3) is an outlet at left back.

Dimitri Payet (27) is nice and close to Enner Valencia (11).

The key thing now is that this shape does not drop too deep.

Mark Noble has run 9.64km as we speak. He is the only player out there to have covered more than 9km.

Enner Valencia and Dimitri Payet almost pull off a one-two which would have seen Valencia with a chance for a hat-trick. It looks like Kelechi Iheanacho is coming on for City.

"I am not having Toure today at all. He is not influential on the ball and not getting up into the box."

Yaya Toure tries to orchestrate from deep. He calls Nicolas Otamendi forward. A ball down the line to Bacary Sagna who digs out a cross and Sergio Aguero's header is flicked wide. A great effort, a fantastic leap at the near post but he just glanced it a little too much.

An offside flag frustrates Sergio Aguero as he eyes a long ball. A brief tantrum from the City scorer.

Victor Moses duels with Raheem Sterling - two ex-Liverpool men. Sterling fouls his man and the home fans cheer the whistle.

There are questions to be asked of City here. Just not enough on show. A title-winning side would probably grind something out here.

"We have seen chances at both ends, but I would say this is West Ham’s game to lose because they are carving out chances."

Enner Valencia has now scored as many goals in his last three Premier League appearances. That's his best three-game run since joining the club.
