became the third American to join German 3. Liga club Sonnenhof Grossaspach when he signed from Borussia Dortmund, where a knee suffered playing for the USA in 2014 derailed a promising career.





Gyau originally hurt his knee during the Landon Donovan farewell game against Ecuador in October 2014, a month after making his debut with Dortmund.



He required meniscus surgery on his left knee, then suffered cartilage damage in training after playing for Borussia Dortmund II in training. He missed all of the 2015-16 season and played twice for Borussia Dortmund II last fall.



Sonnenhof Grossaspach sports director Joannis Koukoutrigas said Gyau's move to the 3. Liga will allow Gyau to continue his comeback without any pressure. Grossaspach is in a five-way tie for sixth place at the winter break.



Charles Renken and Gyau had left the U.S. U-17 residency program in 2009 to sign with German club Hoffenheim. They played at the Vancouver Whitecaps residency academy before turning 18.



Gyau played on loan to second division St. Pauli in 2012-13 and two games for Hoffenheim in the Bundesliga in 2013-14 before signing with Dortmund II. He was promoted to the first team at the start of the 2014-15 season.



Sonnenhof Grossaspach recently signed former U.S. U-23 Mario Rodriguez. Its backup keeper is German-American David Yelldell.
