"I would like to stress that these reports about Naka are complete nonsense," Takuda told the club's official website. "Naka is currently preparing for the Asian Cup but straight after this, is very much looking forward to returning to Celtic.
"He and his family are very happy at Celtic and very happy in Glasgow. He has no reason to go anywhere else."
