LOS ANGELES: Rio 2016 spokesman Mario Andrada on Tuesday (Wednesday in Manila) downplayed concerns over slow ticket sales, saying he expected a late surge would see Summer Olympic venues filled come August. “Brazilians are late buyers,” Andrada told reporters at the US Olympic Committee’s pre-games media summit in Beverly Hills. “Sometimes people get nervous. There is no problem, we are going to sell all the tickets.” Games organizers in Brazil revealed last week that fewer than half of all tickets had been sold with just over five months to go before the opening ceremony on August 5. It was just one more worry for Games organizers already coping with the outbreak of mosquito-transmitted Zika virus and concern over polluted water at the sailing venue at Guanabara Bay.
