Gundogan says it is time for the squad to focus on football, with Die Mannschaft needing to beat Costa Rica in their final group game to have any hope of reaching the knockouts.
“We had a few players who were mad with FIFA, because obviously there were things planned from the team," Gundogan said at Al Bayt Stadium.
“[The armband] getting disallowed just before the game, a few players were disappointed and frustrated and wanted to show something.
"We had the discussion in the team and at the end it got decided that we'll do this gesture against FIFA. If you do something, you do it as a team.
“Honestly, my point of view is now the politics are finished."
Qatari supporters in the crowd last night held up pictures of Mesut Ozil, the former German international, during the game to accuse the Germany team of hypocrisy.
Ozil, a Turkish-German Muslim, retired from the national team after the 2018 World Cup, accusing the federation of racism.
Gundogan added: “We are here now and I think Qatar is very proud. The country of Qatar is very proud to host the World Cup — also as the first Muslim country, and I come from a Muslim family, so the Muslim community is proud.
“Now it's just about football – enjoying and celebrating – so that's the most important thing."
