Rothen said that he is unhappy at being replaced as captain by Yannick Cahuzac half way through last season.
"Hantz decided to challenge my leadership," Rothen told L'Equipe. "Last year, there were two captains, Cahuzac first and me second. "Get me out of that, it's not fair.
"An arrangement needs to be found. I am in contact with the president [Pierre-Marie Geronimi], with whom I have a good relationship. He also wants everything to work out well.
"I have had contact with Nantes and Reims, but I am thinking about things. I must not delude myself, it will be a Ligue 1 club playing for survival or a Ligue 2 club who are trying to win promotion."
Rothen has won 13 caps for France.
