Rennes boss Frederic Antonetti is confident Kader Mangane can be persuaded to stay at the club.
Speculation has suggested that the club captain is generating interest from afar, with Marseille believed to be planning a summer raid.
Mangane is, however, contracted to Rennes until 2013 and they have no intention of allowing him to break that agreement.
Antonetti believes the Senegal international will accept that decision, with it highly unlikely that he will turn his back on a club who value him so highly.
"Kader has two years remaining on his contract and that means we have the final say," Antonetti told L'Equipe.
"The club have made considerable efforts to keep him.
"He is our captain and I don't want to start rebuilding a defence that was so strong last season.
"I have spoken to him and I hope everything will remain as it is."
While Antonetti may have been temporarily distracted by the rumours surrounding Mangane, he is still pushing ahead with his plans to bring fresh faces on board.
He added: "Attacking players will come in so we can manage the squad better than last season. That, though, doesn't mean that the current forwards will be condemned.
"We also need a left full-back because we don't have a real specialist in that area.
"Then we have to think about the midfield. The perfect situation would be to hire six players."
