Schalke chief Horst Heldt remains prepared to sell Lewis Holtby to Tottenham this month.
Holtby has agreed to join Spurs in the summer on a Bosman and Heldt raised the prospect of an immediate sale last week.
An injury suffered by Ibrahim Afellay has led to suggestions of Holtby being kept on, but Heldt insists: "The situation does not decrease our willingness for him to leave early."
