Andre Villas-Boas has confirmed Chelsea and Didier Drogba are having ongoing discussions regarding the Ivorian's future at Stamford Bridge.
Drogba signed for the Blues from Marseille in the summer of 2004 and has netted 149 goals in 320 games for the west London club.
However, with the 33-year-old's current contract set to expire at the end of the season, there has been frequent speculation that his time with Chelsea could be up.
Chelsea, though, are keen to retain the services of Drogba, although the striker's agent has hinted he may target one final pay-day elsewhere before he retires.
And Villas-Boas hopes he can keep hold of the Blues legend for at least one more season.
"It's between a two-year and a one-year and we're waiting to make the best decision possible," said the Chelsea boss.
"We've been discussing this week in week out, the situation is on-going and we hope to solve it.
"Whatever the outcome or agreement, or non-agreement, there will be no question of his professionalism and integrity and he will keep on representing Chelsea this season.
"Didier's importance is straightforward, it's not just because he is performing now.
"The conversation has been on-going since the beginning and we'll continue to push for that. It's not just my decision, it's a decision between two parts and we have to wait and see.
"It's not up to me to speak about what is in Didier's mind at the moment regarding his future. What I think is clear is that he is pretty much involved with Chelsea and his mindset is on competing with his colleagues for this club.
"That's the most gratifying thing, the commitment from the player. His professionalism is not in question."
