Reims chairman Pierre Caillot does not plan to lose a trio of key players during the January transfer window.
Goalkeeper Kossi Agassa, midfielder Grzegorz Krychowiak and forward Floyd Ayite have all impressed during Reims' surprise start to the Ligue 1 season.
The club sit sixth in the table and Caillot is determined to ensure that the squad remains intact through to the end of the season.
"We are not a very famous club, but Kossi is one of the best keepers in Europe," Caillot told L'Equipe. "Even if he is under contract until 2015, he will finish his career with us.
"Floyd is untransferable, full stop.
"Do we have an agreement with Krychowiak to let him leave next summer? He won't leave in January. We really need his physical impact."
