FIFA has opened disciplinary proceedings against Mexico after alleged anti-gay chants by fans during their World Cup win over Germany on Sunday.

Some Mexican supporters chanted a slur when Germany goalkeeper Manuel Neuer prepared to take a goal kick in the 24th minute, and Mexico’s football federation  confirmed that FIFA had informed it of an official investigation. The chant in question is ‘Puto’ which you can see the definition below: 

“In Russia, avoid being detained having your fan Fan ID taken away. Remember that you represent the best fan base in the world,”  says the tweet translated 

“Further updates will be communicated in due course. As proceedings are ongoing please understand we cannot comment further at this stage,” FIFA said in a statement.

FIFA is using a new anti-discrimination procedure for the World Cup, under which referees are instructed to stop the game for an announcement on the public address system when discriminatory behavior is seen or heard. If it continues, the official could suspend the game, and then abandon it if the behavior persists.

“A public announcement was prepared, but the chants ceased,” FIFA said. “After the match and as an important step for further action, the incident was duly included in the match report, as well as the evidence produced by the anti-discrimination observers.”

This is the World Cup, good luck getting anyone to stop chanting whatever the hell they feel like chanting.
