Salomon Kalou insists Chelsea can be proud of their victory over RacingGenk.

Kalou was a second-half substitute in the 5-0 win.

Asked if Genk were one of the worst sides he had faced, Kalou said: "You cannot take away the good performance of Chelsea.

"We played good football and we scored very early, so that gave us also the opportunity to create more chances.

"So I cannot say we played the worst team."
