Chelsea manager Guus Hiddink says his side's push for the Premier League title is now over following their 0-0 draw with Everton on Wednesday.The stalemate leaves them six points adrift of league leaders Manchester United, who also have a game in hand. [LNB]And the Dutchman told BBC Sport: "We said before the match that we could not drop any more points and we have. [LNB]"Mathematically we're in the title race but we have to be honest and focus now on the Champions League and FA Cup." [LNB]The Blues have a Champions League semi-final against Barcelona to look forward to, as well as the FA Cup final against Everton on 30 May. [LNB]And Hiddink says his side must be "more intelligent" in their attacking if they are to succeed in those two competitions where they failed against Everton.[LNB] Who thinks we still stand a chance? At this rate, we'll finish 4th behind Arsenal Drogbas_sniper "We worked hard, but it is not good enough just working hard," he said after the Stamford Bridge clash. [LNB]"We wanted to get it wide and stretch the game but Everton kept a lot of defenders back and made it hard for us - credit to them. [LNB]"At times like that we need to be more intelligent with our play but, in the end, for all our endeavour, we didn't create much." [LNB]However, Hiddink insists his side will not be too downbeat about their title challenge being over. [LNB]He said: "We will have our disappointment tonight, yes, but even though we were in with a shout for the title mathematically before this game, even we knew it would be tough. [LNB]"Now we will face the facts, be realistic, and focus on our other two big events coming up. [LNB]"We have fought for the Premier League as hard as could, but in a few days we have Barcelona and on the horizon the FA Cup, so we have a lot still to play for this season other than the league."
