Reports claimed the Gabon international is set to join Tianjin Quanjian for a €70million move in January.
However, club’s sporting director Michael Zorc has denied the speculation and took a swipe at groundless reports.
"That's completely unfounded. It's only misleading for the fans,'' Zorc told Kickers.
"There are no talks. There are no negotiations, and there's not even indication of it. It puzzles me."
