The last ever league derby between these teams at Upton Park has been pretty quiet so far, hasn't it?

Chelsea goalkeeper coach Christophe Lollichon has been sent from the bench for his protests too. At this rate Jose Mourinho will be the only man left.

"Matic can't have too many arguments. The challenge was late and right under the nose of the assistant referee. Jose Mourinho will be furious his side have lost their discipline."

Jose Mourinho is laughing on the bench as Nemanja Matic trudges off. The Chelsea players have surrounded referee Jon Moss but that won't change his mind, and Cesc Fabregas and Diego Costa are booked for their protests.

Chelsea's day goes from bad to worse. Nemanja Matic tangles with Diafra Sakho down the right and tugs his shirt. He is already on a booking... and he is off.

"Jose Mourinho doesn't look too happy at that offside decision and is letting the fourth official know about it."

That offside decision was not as close as Kurt Zouma's header, but there was not much in it.

Chelsea break again, from a corner and they have men over. Willian feeds Cesc Fabregas on the right and he beats Adrian with a bouncing shot into the opposite corner of the net - but the linesman has his flag up.

"In the old days that definitely would've been a goal. Everyone in the press box here was astonished. When you're watching the replay it looks a goal. Only millimetres have denied Chelsea an equaliser." 

West Ham have been on the back foot for the past few minutes but they almost extend their lead. Manuel Lanzini runs clear, and tries to chip Asmir Begovic. He does... but gets a touch too much on it and lifts the ball over the bar too.

Wow, I've just seen the goal-line graphic showing that Kurt Zouma header. It was a combination of Adrian and then Carl Jenkinson who kept it out - just - about 99% of the ball was over the line, I think. But that 1% is the reason it didn't count.

While Chelsea were appealing, West Ham broke quickly. Cheikhou Kouyat charged over the half-way but was hauled back by Nemanja Matic... who is shown a yellow card.

Another Chelsea corner, another Chelsea chance. Kurt Zouma wins the header at the back post but it is bundled to safety by Carl Jenkinson - I think - with the Blues protesting the ball had crossed the line.

Adrian is busy all of a sudden. This time he dives to his right to keep out a low free-kick from Willian that makes it though the Hammers wall.

Hammers keeper Adrian is called into action for the first time to punch the ball clear at his near post from a corner.

It was West Ham's mistake that let the visitors in, with Carl Jenkinson over-hitting a back-pass that Adrian could not keep in play.

"Initially Jose Mourinho would have been happy with the start, but disgusted by the manner of the goal and the defensively responsibility. Now it means they have to chase the game which he won't enjoy. If they are going to get any kind of form back they need to be defensively solid. Mind you at the other end I can't recall Adrian really being tested yet."

At last, Chelsea advance to the edge of the Hammers box but the home side have plenty of men back. 

Eden Hazard tries to slip the ball through for Ramires down the left but the Belgian over-cooks it and his pass runs straight out of play. That sums up how bad the Blues have been in attack so far.

Still not much of a response from Chelsea. They have not got near the Hammers area since falling behind, but they have had Cesar Azpilicueta booked for fouling Carl Jenkinson.
