In a tale of two West Ham's it's the one that turned up for the second half which was the better of the two and what a dominant performance it was from Big Sam's side.
In the early stages of the first half it was West Ham who settled better at home as expected. The Hammers were pressing high up the pitch early on putting the Chelsea back four under pressure however this didn't last long as the tides then turned when miss firing Fernando Torres was found by Moses with an excellent through ball and he looked up twice and pulled the ball back to Juan Mata who was left out against Fulham in midweek and he placed the ball into the bottom right hand corner of Jussi Jaaskelainen's net.
When the goal went in on the 13th minute the game then turned in Chelsea's favour and they looked much better in possession and were dragging the West Ham midfield all over the pitch. Despite being dominate for the majority of the first half Chelsea didn't create that many chances and despite fluidity with the attacking three in West Ham's half they just lacked a finishing touch which is what Fernando Torres could have given them however when the ball fell to his feet he only managed to find Jussi Jaaskelainen from 10 yards out.
We would all love to know what was said at half time at Upton Park as Big Sam's side came out a completely different to the side which started the first half. Big Sam made two half time substitutions with both James Tomkins and Gary O'Neil making way for Mohamed Diame and Matt Taylor. In the opening stages of the second half you could sense the intent from West Ham as they were much better in the second half with the appearance of Mohamed Diame being the catalyst for West Ham.
Despite all of the talent Chelsea had on offer they couldn't live with a West Ham side who just pressed and pressed with the bit between their teeth and they got the breakthrough through former Chelsea striker Carlton Cole. Cole did look like he climbed on Ivanovic to get his header in however that makes up for Kevin Nolan's goal being disallowed in the first half as James Collins knock down from a free kick which was wrongly ruled as a foul.
Chelsea reacted really well to being dragged back to 1-1 and West Ham were very lucky to get through a brief storm from Rafa Benitez's side which lead to two excellent saves from Jaaskelainen and also Juan Mata's free kick attacked the post and West Ham cleared. The storm from Chelsea only lasted a few minutes before Diame and Nolan got back on possession in midfield and started to dictate the game and Big Sam's substitution played dividends as the big man Diame struck a volley just on the edge of the box perfectly and found the back of the net leaving Chelsea in disarray.
Big Sam's substitutions inspired the side second half and it was proved in added time as pressure from Diame led to Ashley Cole losing the ball with Maiga then finding Taylor, his shot was saved by Cech in the Chelsea goal and then Modibo Maiga who had only been on the pitch for a matter of minutes scored gave Rafa Benitez his first defeat as Chelsea manager in a 3-1 victory for the Hammers.
