Petr Cech admits Chelsea must still rely on a Manchester United meltdown if they are to stand any chance of retaining their Barclays Premier League title.
The Blues kept their desperately-slim hopes of overhauling United alive by beating them 2-1 at Stamford Bridge on Tuesday night to close to within 12 points of the leaders with a game in hand.
Goalkeeper Cech told his official website, www.petr-cech.com: "It is a very important win and it was our only hope of retaining at least some chance of winning the title.
"There are still 33 points in play, so it may happen. But it all depends on Manchester and whether they will feel the effects of this defeat.
"They still have it in their own hands and 12 points is a good lead. We have to keep winning.
"We have just made the first step but we are satisfied with the result and with the fact that we have moved into fourth and are just two points behind Manchester City."
