Marseille could sell defender Cesar Azpilicueta, who has been linked with moves to both Liverpool and Chelsea, as they look to raise funds for new signings.
The Ligue 1 club say either Azpilicueta - rated at £7 million - or Stephane M'Bia could be sold.
Azpilicueta, 22, who is in Britain playing for Spain's Olympics squad, has said he is "flattered" by the link to Chelsea, who have spent heavily this summer as they attempt to build on their Champions League triumph.
Marseille sporting director Jose Anigo told RTL: "Everybody has to sell before buying. In effect, it could either be Stephane M'Bia or Azpi. But, for now, nothing has changed."
