Drogba has been tipped to leave the Blues over the summer, with Milan confirming he is on their list of transfer targets.
But Buck remains hopeful that Drogba will still be in West London next season and is planning to hold talks with the former Marseille man shortly.
''Didier is a superb player generally," Buck told Chelsea TV.
"There have been some comments reported to be made by Didier over the last year that maybe he would like to leave Chelsea. On most occasions he has said that he has been misquoted.
"Now that the season is over, we have to sit down with him and see what the story is and what his future is. He is a great player, I hope he stays, but that is a decision the club and Didier will have to make collectively.
"This year he has had some niggling injuries, but we know he can change the course of a game, as he nearly did in Moscow.
"As I have said, he is a superb player, but if you are a world-class player, which he is, you have to avoid the silly red cards, the ones that come about over nothing - and I think Didier will be sorry that he got that red card."
