Michael Essien accepts Chelsea, despite being top of the pile with a 100% record, still have it all to do. The Blues embark on the quest to lift the European Cup at Wembley in May with a trip to Slovakian minnows MSK Zilina, where they could be without both captain John Terry, because of a rib injury, and midfielder Frank Lampard, just back from a hernia operation, as well as the suspended Didier Drogba.
"We still have a lot to do," said Essien, who netted a brace in Saturday's 3-1 win at West Ham.
"The season is very long, but we have played some good football and are scoring a lot of goals - we have to keep going like that."
