Manchester United midfielder Park Ji-Sung insists his Korea Republic side are capable of defeating Argentina when the unbeaten Group B rivals clash on Thursday at the 2010 FIFA World Cup™.

Argentina, one of the sides tipped to lift the trophy in the final on 11 July, were impressive in their 1-0 win over Nigeria in Johnannesburg on Saturday, while Korea Republic enjoyed a 2-0 win over Greece.

Argentina coach Diego Maradona will be looking to tighten his defence against the live-wire South Korean attack led by Park, who was the man-of-the-match against the Greeks.

Argentina are the best team in our group. But if we play as a team like we did (against Greece) we're capable of getting a result.

The Koreans play La Albiceleste at Soccer City in Johannesburg, and Park says his side have nothing to fear if they can play with the same intensity they produced against Greece. "Argentina are the best team in our group," he said. "But if we play as a team like we did (against Greece) we're capable of getting a result."

Korea Republic coach Huh Jung-Moo said the opening win has boosted his side's confidence, and he believes they can upset a star-studded Argentina team. "We'll give it our best shot, because my players can only grow in stature against opponents of their calibre," said the 55-year-old. "Argentina are among the favourites but we have good players, too. In football, the lesser teams are always capable of beating the bigger ones."
