Dijon fear missing out on Chelsea striker Gael Kakuta.
Kakuta is available on-loan and had agreed to join Dijon.
But Dijon coach Patrice Carteron revealed: "We are in talks with Chelsea.
"I have an agreement with Villas-Boas, but six clubs are interested in the player, including Marseille and Olympiakos, who have put more money on the table."
