Joachim Low was “full of rage” after a selection of Germany’s fans sang Nazi-era songs during a World Cup qualifier against the Czech Republic.
Germany beat the Czechs 2-1 on Friday, edging them closer to qualification for the 2018 World Cup.
The game was overshadowed by some fans interrupting a minute’s silence for two Czech officials who had passed away recently.
The supporters whistled and chanted during the silence, and did the same during the Czech national anthem.
Low was apoplectic after the game, discussing not the performance or result, but the fans.
“I am not so much upset or sad as I am full of rage, I think that describes my feelings better,” he said.
“I am really very angry about what happened, that some so-called fans used the stage of an international football match to bring shame on our country with their extremely embarrassing appearance and behaviour. I think every one of those people who is prevented from getting into the stadium is a win.
“I am absolutely on the side of those demanding tough sanctions, because a stadium should be somewhere you enjoy going, where everybody can go and where despite all the rivalry and all the chanting, everything proceeds at a certain level.
“We don’t want these anarchists, we are not their national team and the behaviour of some of the fans in Prague was the lowest of the low and deeply despicable.”
