Chelsea have opened talks to buy Portugal's Portimonense.
Co-owner Todd Boehly confirmed earlier this month he is wants to set up a stable of clubs and has identified Portugal as a good country in which to buy a satellite team.
Super-agent Jorge Mendes has been consulted over clubs to consider in his homeland and discussions have been held with Portimonense, who are fourth in Portugal's top flight, says the London Evening Standard.
Chelsea's owners are also exploring the possibility of acquiring a club in Belgium, while they have been turned down by French side Sochaux and Brazilian giants Santos.
Chelsea believe an affiliation with other clubs will help give their young players top-level experience elsewhere in Europe.
