TSG-manager Markus Babbel: “It's the right step for Joseph at this point in time. He needs to get some match practice to further develop. With the amount of competition we have in the squad, that just isn't possible here at the moment.”
Gyau, who is a part of the USA's U23 side, moved to Hoffenheim in July 2010, joining the U19 squad. In the 2011/12 season, the attacking midfielder made the jump to TSG's U23 fourth division side.
