West Ham 2-1 Man City
Alex Song gets a bit of space in midfield. He will shoot but surely not score? What could be more rare than a Song goal? Wide. A good hit but a foot or two the wrong side.

Michail Antonio gets a round of applause as he leaves the field for Victor Moses.
West Ham 2-1 Man City
Can Manchester City find another gear. They've been in neutral for large parts today but don't look like they've got a great deal of zip to their play.
West Ham have run 73 kilometers as a team, City just 70km. It's showing.
Adrian boots one clear and again the second ball is picked up by the home side. Aaron Cresswell will cross low, Yaya Toure has to slide to clear.
West Ham 2-1 Man City
Alex Song is wearing protective goggles today after being poked in the eye during training. He certainly has the Edgar Davids looks about him.

Steve Brown
Former West Ham reserve-team coach on BBC Radio London
"That is as poor a goal as you will see in the Premier league all afternoon. It is a monster throw in and he is just not picked up. That is not acceptable at this level."

Eamonn McGurk: That's Sunday League stuff from City!
KJTraining: Otamendi looks out of his depth in the PL, notably in away games. It takes foreign defenders a season to adapt.(See Koscielny)
West Ham 2-1 Man City
Kevin de Bruyne down the inside-left channel... shoots... blocked. Jesus Navas in the same position... blocked.

"Utterly horrendous defending from Manchester City. Routine throw in and Otamendi dopey - didn't seem to realise Valencia was there."
West Ham 2-1 Man City
Dear me. Nicolas Otamendi, hang your head in shame.
The central defender switches off and Michail Antonio takes a long throw straight into the path of Enner Valencia who collects a bouncing ball eight yards from goal and prods home. That's his second.
A strange, strange goal. A throw in over the top if you will. Coming to a Sunday league pitch near you tomorrow for sure. Horrendous defending.

West Ham 1-1 Man City
David Silva is strolling around, connecting play like a human extension cable.
He doesn't sprint, simply gives it, gets it back, looking for an opening.
Good patient stuff but Fabian Delph injects some pace... he shoots left footed, it's low... off the foot of the post.

Quinn Garrity: Aguero playing well but should have a couple of goals to his name!
Ponder: As a Hammer, my first reaction to the Demichelis' challenge was yellow, due to covering defenders. Very, very cynical though.
Kayciey: Red card all day for Demichelis. Refs very partisan in the title challenge.
West Ham 1-1 Man City
Dimitri Payet has played 29 passes, only four have gone astray. Of the heavily involved players on show he's out in front in terms of accuracy.
Impressive throughout.
West Ham 1-1 Man City
Dimitri Payet swings in a corner which evades bodies and gets cleared in a panic at the back post. They come again, West Ham link nicely as Dimitri Payet feeds Mark Noble... deep cross to Michail Antonio who heads wide.
That's a real chance. He out-jumped Bacary Sagna.
West Ham 1-1 Man City
Yaya Toure gives a free-kick the big build up and crashes the ball into the wall. Bang average.
West Ham 1-1 Man City
Bubbles again at the Boleyn. Not many more famous nights to be had here. Can they land a big fish in beating City. We are underway.
West Ham 1-1 Man City
The players are back in the tunnel and West Ham boss Slaven Bilic is having words with Craig Pawson. He was not happy with the referee's decision to only book Martin Demichelis earlier when the Argentine hauled Michail Antonio down.
West Ham 1-1 Man City
It may be 1-1 on the pitch, but it West Ham easily won the pre-game war of words.
For some of you who don't watch TV, Joe Hart advertises an 'anti-dandruff' shampoo.
