Goals from Nicolas Anelka and Daniel Sturridge saw Chelsea safely through to the fifth round of the FA Cup with a 2-0 win over Preston at Deepdale.
Anelka made the breakthrough in the 36th minute but Darren Carter should have equalised for Preston only to send his shot the wrong side of the post from close range.
That proved to be the turning point with Sturridge extending Chelsea's lead in the 47th minute after John Terry's header had been blocked.
