Petr Cech insists that Chelsea are still convinced the incredible feat of a Premier League and Champions League double is on the cards.

The Blues keeper said: "It is extraordinary. What a time is coming now! We don't think the League is over and we want to keep pushing Manchester United - and of course in three weeks it will be incredible when we meet them in Moscow."

Cech believes it will suit Chelsea that United, who still lead them on goal difference in the League, have to play West Ham on Saturday lunchtime while they have the weekend to relax and prepare for Monday's clash at Newcastle.

"We will know exactly what we need to do after the weekend and it could be a big advantage," he said. "But nothing really changes for us. We know we still have to win both games and we believe we will."

Chelsea will round off their Premier League campaign at home to Bolton while Manchester United go to Wigan.
