West Ham United battled back to sink Rafa Benitez's Chelsea 3-1 at Upton Park.
The visitors led at half-time after Fernando Torres set up Juan Mata for a slick finish.
But Sam Allardyce's side equalised in the second half when Carlton Cole headed home Matt Jarvis's cross.
The hosts took the lead after 86 minutes when Mohamed Diame lashed an effort into the net.
West Ham sealed a memorable win over Chelsea in injury time when Modibo Maiga netted to seal another miserable day for Benitez.
