The Ivorian's current deal expires at the end of the season but he believes that he has a future at Stamford Bridge.
"I want to stay, I want to be here," he said after he scored in his side's 5-0 Champions League win against Genk. "I like Chelsea - I have had a fantastic five seasons here and won some prizes.
"Chelsea are looking forward to the future, I am still a young player and I think my future can be here."
The 26-year-old moved to the Premier League side from Dutch club Feyenoord in May 2006.
