LAST MEETING
September 11, 2010: West Ham 1-3 Chelsea
Chelsea continued their fine start to the season by cruising past West Ham thanks to a Michael Essien brace and Salomon Kalou's strike to stay top of the league and condemn the Hammers to the bottom of the table.
PROBABLE LINE-UPS
Chelsea: Cech; Ivanovic, Terry, David Luiz, Cole; Essien, Ramires, Lampard; Anelka, Drogba, Malouda.
West Ham: Green; Jacobsen, Da Costa, Upson, Bridge; O'Neil, Noble, Parker, Hitzlsperger; Cole, Keane.
Prediction
The form book suggests only one outcome at Stamford Bridge. Chelsea have quietly put together a run of form which has seen them re-emerge as outsiders in the title race. They should be far too strong for Avram Grant's side, who are without a win in five games in all competitions.
Chelsea 3-1 West Ham
