Bordeaux president Jean-Louis Triaud is not prepared to get dragged into a 'war' regarding Alou Diarra.
The midfielder remains a target for Ligue 1 rivals Marseille, who have openly courted the 29-year-old throughout the summer.
Bordeaux are reluctant to see their skipper leave, but have been forced to accept that there is little they can do to make him stay.
As a result, Triaud has revealed that he will not stand in Diarra's way should he wish to leave, but has made it clear that Marseille must meet a €7.75million (£6.5m) release clause in order to get their man.
"He (OM president Jean-Claude Dassier) called me yesterday in the evening," Triaud told L'Equipe.
"We would prefer to keep Alou Diarra, the captain of our team.
"But there is an option for him to go and they all know it - the player and the club (Marseille).
"Me, I will respect the word that has been given.
"But if he insists on leaving, we will not get into a war with Alou Diarra.
"What is necessary is that Marseille must be a bit more professional because for now they say they are interested in a player, but they must decide quickly."
While prepared to let Diarra leave if the France international makes it clear he wants out, Triaud has no plans to compromise over the release clause involved in the deal.
"Are you kidding or what?" he said when asked about the possibility. "There is no reason to.
"If he goes, we will have the cash to do something else. They know the conditions."
