RIO DE JANEIRO -- When a BBC announcer suggested that a Brazilian broadcaster needed to shut up at the start of a swimming race at the Rio Olympics, he was voicing the feelings of many in the host country.Considered the Bob Costas of Brazil, Carlos Eduardo dos Santos Galvao Bueno -- known here simply as Galvao -- is a love-him-or-hate-him announcer who is the voice of Brazilian sports. His raucous, over-the-top style helps make big sporting events feel even bigger in Brazil.But those who dislike Galvaos clamorous colloquies have taken to social media during the Olympics to beg him to be a bit more silent and are reveling in the outside criticism. (hash)CalaABocaGalvao is a thing. Translation: Shut up, Galvao.Sometimes I change channels so I dont hear you, one Brazilian watcher said on social media.Galvao, 66, is the chief sports commentator for Globo, a major television network in Brazil. Hes the voice that brings World Cups, Formula One races and, of course, Olympic Games to millions of Brazilians. Beyond his seeming inability to take a breath, hes known for his blind support of Brazilian athletes, blunt disagreements with guests and fellow commentators, and excessive attention to the rivalry between Brazil and Argentina.Among his signature sayings: Winning is great, but beating Argentina is much better. These (insert nationality of opposing team here) are very annoying. Dramaaaaaaaaatic! And the oft-heard Haja coracao -- something akin to feeling like one might have a heart attack -- now a common saying expressed by Brazilians during sporting events.Galvao already was getting attention for a scathing commentary after Brazils Olympic mens soccer team could manage only a 0-0 draw against Iraq and walked off the field without talking to reporters. Ugly. Very ugly. ... Not professional. ... Unethical, Galvao said on air.The swimming incident circulated on Twitter when a video of the BBC broadcast was posted. Before one of the many races featuring Michael Phelps last week, Galvao kept talking -- loudly -- as the swimmers took their starting positions. When an official paused to ask the crowd to quiet down, the BBC commentator said, Too much noise ... at least coming from the commentator next to me. I tell you, he needs to shut up during the start.After the incident, Galvao acknowledged he should have zipped his lips and posted a picture on Instagram of him with the BBC broadcast team.Here are the Globo and BBC teams together. The bald man is Seoul 1988 Olympic champion Adrian Moorhouse. A colleague from other Olympics. My voice leaked into his microphone and they complained. I was wrong. I should have remained silent at the start. End of the whining, he said.Another Galvao broadcast has since gone viral, as well: His account of Phelps victory in the 100-meter butterfly at the Beijing Olympics in 2008.He is going to win, he is going to lose, he is going to win, he is going to lose. He lost ... HE WON! a waffling Galvao howled during the Globo broadcast.Despite all the mockery, some find Galvao inspiring. Local Fox Sports announcer Gustavo Villani is one.He truly understands all sports and delivers it with a lot of emotion, Villani said. He lets himself go. LYON, France -- Russian hooligan groups are planning to cause significant fear at the 2018 World Cup following violent attacks and racist behavior at the European Championship, anti-discrimination organization the Fare Network has warned.In a report analyzing cases of racism and discrimination at Euro 2016, the UEFA-affiliated Fare Network says fans of eight of the 24 teams at the tournament, including England, were involved in discriminatory incidents in and around stadiums.The incidents range from racist and homophobic slogans to the mass street violence involving English and Russian fans in Marseille ahead of a group stage game between the two countries last month.Fare, which posted observers at Euro 2016 games, says well-organized Russian hooligan groups with racist links may be tempted by the prospect of causing isolated harm and creating significant fear during the Confederations Cup 2017 or World Cup in 2018 and calls on the Russian government to do more to stop them.We remain concerned about the prospect of ongoing far-right involvement in Russian football, the report says. This and the organized nature of their hooligan groups -- as seen through the levels of violence they used in Marseille in particular -- need addressing urgently by Russian authorities.Fare says it has significant concerns that fans of a visible African or Asian heritage or those from the LGBT community could be attacked if they visit some World Cup host cities.After the violence in Marseille, three Russian fans were sentenced to prison terms of between one and two years, while 20 more were deportedd from France, including a fan leader with a role in organizing World Cup preparations on a Moscow city government commission.ddddddddddddBesides street violence, Fare says some Russia fans wore clothes with racist symbols, displayed far-right banners at a game and were reportedly performing monkey chants toward stewards.Some England fans were also seen chanting sexist and xenophobic anti-migrant chants, and filmed mocking children from the Roma minority, also known as Gypsies, by throwing coins for them to chase.Croatia also comes in for heavy criticism by Fare, which highlights cases at three separate games in which fans chanted or displayed flags in support of the World War Two-era Ustase fascist movement. Meanwhile, a group of German fans performed Nazi salutes and attacked Ukrainian supporters ahead of a group stage game, according to the report.Fans from Spain, Poland, Ukraine and Hungary were also censured for racism-related conduct.Despite highlighting discriminatory conduct by eight teams fans, Fare says that UEFA punishments for teams had prevented more incidents.The overall levels of major discriminatory incidents recorded inside stadiums were not as high as they could be and have been at other tournaments, the report says. Fan conversations that we monitor on social media and message boards often follow a line that certain banners and chants should be kept to matches at national level to avoid risk of severe collective sanction from UEFA.
