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."
