The 34-year-old's current deal at Stamford Bridge is due to expire at the end of the season and so far both parties have been unable to reach an agreement over an extension.
Despite insisting that Drogba has another couple of years at the top level, agent Thierno Seydi was unable to confirm that the Ivory Coast international will finish his career with the Blues.
"I don't know if he will remain at Chelsea next season," Seydi told L'Equipe. "But I know Didier could easily still play two years in a very big club.
"His secret? Recuperation. Didier takes a lot of care of himself, and he recuperates quickly and very well."
Drogba is expected to start up front for Chelsea in the Nou Camp this evening.
