Chelsea went back on top of the Premier League after hammering West Brom 3-0 at the Hawthorns to secure a record tenth successive away league win.
Nicolas Anelka continued his scoring streak with an excellent first half brace. The French striker's form means that Didier Drogba is having to make do with a place on the bench.
Blues' boss Scolari was full of praise for the former Bolton hitman: "Nicolas has more confidence and the other players have more confidence in him. So they are giving him more chances to score."
West Brom started well and threatened Cech's goal early on, but they went behind after Scott Carson failed to deal with Bosingwa's curling shot from the edge of the box. Anelka scored Chelsea's second goal soon after to put the game beyond the Baggies.
