Manchester United midfielder Park Ji-sung was delighted with South Korea's victory over Greece.

The 29-year-old Manchester United midfielder scored as South Korea kicked off their Group B campaign with a comfortable 2-0 win over Greece to set themselves up perfectly for their clash with Diego Maradona's men in Johannesburg.

Park said: "Argentina is, of course, the strongest team in our group and people are saying they could make the final. They have a lot of top international players."

He added: "Before the World Cup, we played a friendly against Spain and we thought about Argentina as we were playing that game.

"Of course, there is a lot of difference between the two teams, but the unexpected can happen in this World Cup, and that is what we are looking to do."
