Chelsea striker Didier Drogba says he won't be firing on all cylinders for some weeks.

After his comeback in Saturday's win at Manchester City, Drogba said: "My over-riding priority is to play without pain in my knee.

"All I would say is that I don't want to get ahead of myself and do too much too soon. However, I'm certain that Chelsea are growing in power and we'll do everything we possibly can to win the Champions League this season."
