The Guinea international’s current contract with Stuttgart is set to expire at the end of the season.
Traore has become a first-team regular at Stuttgart, since joining the club from Augsburg in 2011.
“We are out to keep Ibo at our club,” Stuttgart’s general manager Fredi Bobic told BILD.
“We have had talks with him and his agent. We have told them our point of view.
“Up to now, we have not yet reached an agreement on a new contract.”
