Drogba said: "The most important thing is to win the Premier League or Champions League, and I think we have a good chance to do both, even if it isn't going to be easy.
"We are trying to fight for the title. It's more exciting when you have a lot of intensity in each competition."
Kalou said: "The title is all to play for. We have always thought so.
"When you are second in the table of the best League on the planet and only three points behind Manchester United, you certainly can't say you're having a bad season.
"Of course, there's no room for error. There are five games left and we have got to do everything to put United under pressure."
