Lewis Holtby's agent has admitted the Tottenham midfielder is "desperate to play" and could look for a move elsewhere in the January transfer window.
Holtby's committed performances have made him a popular figure with the Spurs faithful but the German has struggled to establish himself in the Tottenham first team.
He has been linked with a return to former club Schalke.
"Lewis is desperate to play, which is why we are looking intensively for solutions," Noack told Bild.
"Schalke is an interesting option."
