Didier Drogba will be missing for two weeks from Chelsea after scans on a knee injury showed that it was more serious than first believed.

The Ivorian was his top scorer last season with 33 goals and offers the team its focal point. Drogba damaged the knee in training on Saturday and there are fears that he will miss not only the opening games of the season against Birmingham and Reading away next Tuesday but also the visit to Liverpool the following Saturday.

With John Terry, the captain, already ruled out for four weeks with a knee ligament injury, Jose Mourinho can ill afford to be without another of the team's leaders.
