Reims president Jean-Pierre Caillot is willing to sell Boulaye Dia in January.
Dia is being linked with Newcastle United and Brighton.
Caillot has admitted he has given Dia his word that he will be allowed to leave if a suitable offer comes in for him.
“(Dia) could have left this summer (but) he did not leave because he did not receive the offer he wanted," he told Top Mercato. "Boulaye refused two offers, from Lokomotiv Moscow and Hellas Verona. For various reasons, he did not want to go to these clubs.
“If he stays (beyond January), I would be delighted. If he has an offer that suits him and us too, I could not object because I gave him my word."
