Chelsea manager Guus Hiddink admitted his side's Premier League title hopes had vanished after the goalless draw against Everton at Stamford Bridge.
The stalemate, coupled with Manchester United's 2-0 victory against Portsmouth, has left Hiddink's side six points behind the league leaders who also have a game in hand.
The experienced Dutch coach said after the game: "We said before the match that we could not drop any more points and we have.
"Mathematically we're in the title race but we have to be honest and focus now on the Champions League and FA Cup.
"There was desire and we started the game rather well.
"But after the first 20-25 minutes when we didn't score despite playing well, we tried even harder and we lost positions and patience.
"I am not saying we have to play slowly at that moment but you have to maintain your positions and try not to force it. Then automatically the chances will come. We didn't do so.
"In the second half we were working hard. You could not blame the team for not working hard but they needed intelligence to break Everton's well-organised wall of defence. They had some dangerous counter-attacks as well."
