Cameron Jerome and Robert Huth eased Stoke into the fifth round of the FA Cup with a 2-0 victory over a lacklustre Derby.
Striker Jerome's close-range effort in the fifth minute and centre -back Huth's 81st-minute volley comfortably saw the Potters home at Pride Park.
Derby, who had won their previous five league and cup matches on home soil, barely mustered anything of note as goalkeeper Asmir Begovic enjoyed what was virtually an afternoon off.
