Lille have informed Chelsea they're prepared to sell Thiago Mendes next month.
Last summer, Chelsea asked Lille to keep them informed of the Brazilian's situation with the view to bringing him to England.
RMC says Lille have told suitors they're prepared to sell Thiago Mendes in January.
Chelsea are in contact, along with Wolfsburg and Schalke 04.
PSG are also interested in the midfielder, who they see as a replacement for contract rebel Adrien Rabiot.
