Brazilian soccer star Adriano says the South Korean national team is "dangerous."

Representing his nation at the ceremony to unveil countries' uniforms for the World Cup Monday in Berlin, he said Brazil should beware of South Korea's strength given the many talented players the team has.

Dutch star Ruud Van Nistelrooy hailed Manchester United teammate Park Ji-sung as South Korea's best player who will lead his nation with Tottenham Hotspur defender Lee Young-pyo.
