Ghanaian duo Charles Takyi and ex-international Otto Addo have signed up with Germany's political party SPD to fight racism from the sport.
The two players were joined by Hamburg's mayor at the SPD party headquarters and held a shield with the inscription "Respect! No place for racism".
Takyi, a striker for German Bundesliga II side St Pauli, early this week applied to Fifa for a national switch to play for Ghana.
He played in St Pauli's Bundesliga campaign last season but got relegated.
Ghana's Fifa 2006 World Cup squad member Addo has ventured into coaching since retiring from the sport and won the German youth trophy with Hamburg's Under-19 side.
The Social Democratic Party is Germany's oldest political party, established in 1875, in the German Parliament.
