The 25-year-old -- who will play up front on the left flank -- tore ligaments in his left ankle in the final friendly (a 6-1 thrashing of Armenia) before the World Cup which Germany went on to win.

He missed the German SuperCup on Wednesday which saw Dortmund beat a weakened Bayern Munich 2-0 with Henrikh Mkitaryan and Pierre-Emerick Aubameyang scoring.
