West Ham United 3-1 Chelsea
1 December 2012

Carlton Cole got the comeback started with a 63rd minute equaliser before late finishes from Mohamed Diame and Modibo Maiga set the seal on a triumphant Boleyn Ground afternoon.

West Ham United 1-0 Chelsea
3 May 2003
Prior to last season's victory, West Ham's last home win over Chelsea came back on the final day of the 2002/03 season.
The Hammers, under the temporary charge of Trevor Brooking, were deep in relegation danger but in the midst of a great run of form which gave them a chance of escaping.
Paolo Di Canio's 71st minute goal gave them the points and took the fight to the final day, but a 2-2 draw at Birmingham was not enough to save them, despite amassing 42 points.
West Ham United 2-1 Chelsea
24 October 2001
All the goals came early on in this midweek meeting between the clubs, as West Ham emerged triumphant by the odd goal in three.
Just five minutes were on the clock when Michael Carrick gave the Hammers the lead, then Frederic Kanoute doubled the advantage eight minutes later.
Jimmy Floyd Hasselbaink got Chelsea back in it midway through the first half, but surprisingly that was where the scoring ended as the Hammers moved up to 14th in the table.
West Ham would eventually end the campaign in seventh, just one place behind their visitors.

West Ham United 3-2 Chelsea
13 March 1997
This was a real see-saw battle, which both sides harboured ambitions of winning, until Paul Kitson struck late on to settle the matter.
Chelsea were first to edge in front through Gianluca Vialli in the 26th minute, but a Julian Dicks penalty ten minutes after half-time levelled things up.
Then it was West Ham's turn to lead as Kitson scored his first of the game, but Chelsea looked to have rescued a point when Mark Hughes notched three minutes from the end.
The Hammers were unbowed though and Kitson scored again to keep all three points in east London.
