Chelsea's Didier Droga suffers ankle injury one week before season

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.
