Chelsea kept up their impeccable start to the season, hardly breaking sweat as they brushed aside a West Ham side who remain rock bottom of the table.
Michael Essien put the Blues in front inside two minutes with a free header.
And the second goal arrived in bizarre fashion as Matthew Upson’s clearance struck Salomon Kalou’s heel and ballooned into the net.
Essien rose above Tal Ben Haim to add a late third, before Scott Parker lobbed Petr Cech from the edge of the box.
