Tottenham Hotspur have announced that they have reached agreement with Schalke for the immediate transfer of midfielder Lewis Holtby.
The Germany Under-21 captain, who has three senior caps, had initially agreed to join Andre Villas-Boas's side in the summer but the Barclays Premier League club decided to bring the move forward in order for the 22-year-old to aid their bid to secure UEFA Champions League football next season.
The versatile midfielder joined Schalke in 2009 and was loaned out to Bochum and Mainz before becoming a first team regular.
Holtby, who has an English father, has made 160 appearances in his career to date, including 18 appearances in the German top-flight this season. He has scored 29 goals in total, four of them in the Bundesliga this campaign, and also played against Arsenal twice in this season's Champions League group stages.
