Chelsea striker Didier Drogba has sparked doubt over his fitness ahead of the new season after suffering an ankle injury in last night's pre-season friendly against Ferencvaros.

The Ivorian, who rejoined the Blues last month by signing a one-year deal, limped off the field after 28 minutes into the match.

The 36-year-old received treatment on his ankle before Chelsea came from behind to seal a 2-1 victory over the Hungarian side courtesy of a winning goal from Cesc Fabregas.

The West London outfit will open their Premier League campaign against Burnley this weekend.
