Marseille sporting director Jose Anigo has admitted that the club will listen to offers for Chelsea target Cesar Azpilicueta.
The European Champions have been linked with the right-back on a number of occasions this summer and Marseille have now accepted that they will need to sell players in the current transfer window.
Anigo told RTL: "Everybody has to sell before buying.
"In effect, it could either be (Stephane) M'Bia and Azpi. But for now, nothing has changed."
Roberto Di Matteo is searching for a new full-back after releasing Jose Bosingwa last month.
