Agent Thierno Seidy is confident Chelsea will extend his eight year stay with the Blues after admitting the two parties are talking.
"Talks are going on with executive director (Ron Gourlay), and we will take stock with him before the end of the season," Seidy told L'Equipe.
"I believe what Didier is currently showing will lead the club to a new thought. Didier loves Chelsea and he wants to stay, but if things have to happen another way, he will leave. This time, we can make the decision by ourselves.
"Didier will be a free agent at the end of the season, so he is master of his own fate to sign his last contract."
