Chelsea boss Carlo Ancelotti believes they can end Arsenal's title challenge tomorrow.

Chelsea will go nine points clear of Arsenal if they beat their rivals.

Ancelotti said: "Arsenal have very good quality in midfield, fantastic players with strong quality - Fabregas, Arshavin and Nasri - but we didn't give them the possibility to play easily.

"It's all important to put pressure on them with our midfield and not leave space.

"If we win it will be difficult for them to return to the top.

"They are involved in the Champions League, too, so it could be very difficult for them to stay in touch with Chelsea and United."
