According to German media ARD (German Public Broadcasting Union), only Neuer and Gretzka expressed support for the previous protest by covering their mouths before the game.
Previously, FIFA official regulations do not allow the wearing of rainbow armbands, if you wear it, you will get a yellow card in the competition. After the match between Germany and Japan, the German players covered their mouths in protest when they took a group photo before the match.
German media ARD said that only Neuer and Gretzka expressed support for the move, and the rest of the players, like other countries, did nothing.
Bild confirmed that Neuer and Gretzka did promote the discussion of whether to cover their mouths and put forward a number of ideas. It is said that other players protested against doing anything at that time.
After the discussion, Kimishi also expressed support for the mouth-covering protest, which was finally chosen, although it was not all recognized in the German team.
