Joe Hart leaves the field laughing and joking with the referee and his assistants. He probably wants to burn off some energy because he has had practically nothing to do. It's his birthday and he'll stand around not having to make saves if he wants to.

There is no out-ball for West Ham. Every time they clear a City attack, the ball comes straight back as part of another home attack. Even Adrian is put under pressure and is forced to turn away from Jesus Navas before clearing. Just the one minute to be added before the Hammers get a much-needed 15 minutes to regroup.

Liam O'Connor: Can a Hammers fan please tell me what happened there season? At the start they were exciting, dynamic and lovely to watch. Now?

Terry Lambert: West Ham looking like Spurs at Man City. Asking for a beating. So poor it is unbelievable. Players have gone on holiday already.

You have to wonder just what has happened to West Ham this season? During the early months they were an exciting attacking side, giving some of the best in the division a decent game. In contrast, this is a timid, almost apathetic display from them littered with mis-placed passes and poor control.

"Manchester City are ripping through West Ham time and again. If the away side aren't careful this could turn into a very heavy score line. City are moving the ball quickly across the visitors' defence before stepping up the tempo another notch with a killer ball. A win would take them seven points clear of Liverpool and that should secure them Champions League football."

This could get embarrassing for West Ham. City have the bit between their teeth and are constantly probing on the edge of the Hammers box. Frank Lampard gets a chance to cross but over-hits it and the ball sails out of play on the left touchline.

"That is what this Manchester City side can do when they are in full flow. They just swarmed forward on the break. There were four players up in support of Sergio Aguero, whose composed slide under the goalkeeper puts City 2-0 up."

Sergio Aguero's first century of City goals is complete and now he has begun his quest for a second. It is a lightning break away, which sees Yaya Toure win the ball from Stewart Downing, Aguero carry it and find Jesus Navas before collecting the return ball in the box for a finish under Adrian. It is a long way back for West Ham now.

Frank Lampard has been making late runs into the box for about two decades now. He performs yet another to try and reach a flick from David Silva but is denied by a diving tackle from a West Ham defender. As the Hammers look to break, Alex Song is fouled by Jesus Navas for the game's first booking.

"Manchester City are dominating play and even more to their credit, as soon as they lose the ball they are intent on winning it back straight away. West Ham are at least getting up the pitch a bit more now though. Carlton Cole had no support at all in the first 20 minutes."

West Ham look to capitalise on their superior numbers but Enner Valencia's low drive from outside the box is saved by Joe Hart. Zabaleta returns - nose clean - and City are back up to 11 men.

Birthday boy Joe Hart comes to the rescue after a hesitant piece of defending from martin Demichelis gifts the ball to Carlton Cole in the City half. Cole looks to charge into the home box from an angle on the left but Hart is quickly out to meet him and block. City are currently down to 10 men as Pablo Zabaleta has a bloody nose cleaned up.

Normal service is resumed as City pour forward again. A chip to the right byline is met by Jesus Navas, whose drilled volleyed cross finds David Silva. The midfielder controls and shoots but his effort is blocked. That could easily have been 2-0.

West Ham have a rare chance to create something as Stewart Downing gets the ball in acres of space on the right but his cross into the middle is way over the heads of three breaking team-mates. To be fair, even if they had reached that, an assistant's flag would have greeted them for offside.

Adam Bevan: What a finish James Collins! Take a bow/hang your head in shame.

Schoolboy J: One of the best own goals you will ever see. Collins like a boss!

West ham look to claw their way back into the game from their second corner but a tame header from a corner drops comfortably for Joe Hart to gather. Big Sam is already slumped down in his seat, arms folded and chewing furiously on a piece of gum. This could be a long afternoon.

The goal may have come from fortuitous circumstances but you can't deny that City have dominated the early stages of this game. There is a real attacking intent about their play, no doubt intended to make some amends for recent weeks.

"James Collins just got his footing wrong. The ball sliced off him and in off the underside of the crossbar. On the balance of play that is no surprise. West Ham have showed Manchester City too much respect. They've not been in their face at all. City can now pick them off at will."

Well, it has been coming. Not like this, though. Jesus Navas wins a header on halfway and charges into West Ham territory before curling a cross that James Collins slices over his own keeper and in off the bar from 18 yards out. It's a great finish, from City's point of view. A horror moment for the Hammers.
