Chelsea fullback Jose Bosingwa says they can stop Portugal teammate Cristiano Ronaldo at Manchester United on Sunday.

Bosingwa said: "To stop Cristiano is not easy but at Chelsea there are people who know him well, including the manager.

"We know what to do to stop him putting on a show."

Chelsea have taken only 10 points from their last seven League games - including draws with West Ham and Fulham. And last Saturday they were held by League One also-rans Southend in the FA Cup.

Bosingwa said: "Some people are beginning to doubt our chances for the title, but we want to leave Manchester proving that there is a lot still be to be decided.

"This game is very important for our fight for the title. United are coming from behind and are pressing hard and the game will not be easy.

"But we plan to go there and claim victory. It would be a big boost for morale if we got three points. And we know whatever happens we cannot stop fighting for our target."
