Chelsea youngster Gael Kakuta has reportedly become a target for Olympiakos and French club Marseille.
Kakuta has previously been strongly linked with a loan spell at Ligue 1 club Dijon.
The 22-year-old spent last season on loan at Fulham before being farmed out to Bolton this term – where he has so far failed to make a full start.
Kakuta arrived at Stamford Bridge in 2007 from his boyhood club Lens.
