Borussia Dortmund have completed the signing of Tottenham midfielder Kevin Prince-Boateng on a sixth-month loan deal. The German-Ghanaian's contract with Dortmund allows him to permanently join the Bundesliga side if the two teams agree a transfer fee comes the end of the season. Boateng failed to establish himself as a starter since joining Tottenham from Hertha Berlin for around $10 million in the summer of 2007. The 21-year-old played 13 times for the north London side last season and just once this term.
