Chelsea striker Didier Drogba has successfully undergone surgery on a groin injury that had troubled him last season, although his recovery and rehabilitation from the operation could make it touch-and-go whether he will be fully fit in time to help the Blues' when they commence their Premier League title defense at home to West Bromwich Albion on 14 August.
Despite the lingering injury the prolific target-man still fired the Blues to a domestic double during 2009-10, contributing 29 Premier League goals in 31 starts.
