A decision from Chelsea boss Andre Villas-Boas is expected before weekend over the future of Slobodan Rajkovic.
Rajkovic is waiting to hear whether his UK work permit application will be accepted.
L'Equipe says the Serbia defender agreed a loan move to France's Valenciennes last week, but Villas-Boas has told the youngster to wait another week before a decision is made.
Villas-Boas has been delighted with Rajkovic's form in preseason, but knows his lack of international caps is working against the player in his bid to gain a UK work permit.
