Singapore: Brazil coach Dunga denied on Monday insinuating drug use in the Argentina camp after he was filmed pinching his nose and pointing at the rival bench during the weekend win in Beijing.

Dunga, questioned over the incident during Brazil's trip to Singapore, said he was making reference to severe pollution in the Chinese capital which gave players blocked noses. Saturday's "Superclasico" friendly was anything but, as a fired-up Brazil won 2-0 to restore pride against their fierce rivals following a poor World Cup campaign on home soil.
