BERLIN - Japanese international Shinji Kagawa has re-signed for former club Borussia Dortmund for a reported fee of 8million euros ($10.5million, £6.3million) ending an unhappy two year spell with Manchester United German publication Bild claimed on Sunday. The 25-year-old midfielder -- who played 71 games for United including 39 in the Premier League after moving there for 16million euros -- has signed a four year contract with the German giants, with whom he won the 2012 domestic double as well as the 2011 league title after he joined them for just 350,000 euros in 2010. Kagawa, part of the Japanese squad that failed to fire at the World Cup finals, had looked to have a shaky future at United with their Dutch manager Louis van Gaal saying he did not fit his philosophy of football.–AFP
