Lewis Holtby moves to Tottenham with the best wishes of Schalke.
Schalke director of sport Horst Heldt has wished Holtby the best of luck at Spurs.
"We have found the best solution for all involved," he said on his club's website.
"Lewis had hinted to us that he would not be against moving immediately, and Schalke have received a decent sum for a player whose contract was due to expire in five months.
"We wish Lewis all the best for the future."
Holtby's last appearance for Schalke, whom he joined in 2009 from Alemannia Aachen, came in Saturday's 0-0 draw at Augsburg.
"He always behaved correctly and gave it all he had got for Schalke until the very last day," added Heldt.
