Frank Lampard says Chelsea must buck up if Didier Drogba is ruled out for a lengthy time following his knee injury.

Lampard said: "If Didier is out for a while, we will just have to get by. We will have to pitch in with goals from all around the team, which we can do, though the situation is not ideal.

"Nicolas is a top-class striker, and we also have Salomon (Kalou) and young Franco di Santo. The experience is not really there, but I believe the quality is.

"Hearing about Didier was the bad news of the day because he is so important to us. He has been out before with a knee injury. We hope he can be back as soon as possible."
