South Korea midfielder Park Ji-Sung believes their impressive performance against France is proof they need not fear Switzerland in tonight's make-or-break Group G decider.

Dick Advocaat's side has vowed to treat the game as a must-win encounter in Hanover, although a draw may be enough to qualify for the knockout stage and certain permutations would even see teams having to be separated by the drawing of lots.

It could become very complicated but the Manchester United man, who has recovered from an ankle injury, insisted he could see the picture very clearly.

He said: "The one thing we have to do is win. We want to be in control of the match and attack all the time. We believe that we will win tonight.

"We are all feeling very confident - just as we did for the France game."

That had ended 1-1 in Leipzig, with Park popping up with a late equaliser to wipe out Thierry Henry's opener.

The Swiss currently top the group, ahead of the Koreans only on goal difference. France are two points behind so know only a resounding win against Togo in Cologne will guarantee them qualification.

A goalless draw allied to a 2-1 win for France would trigger a lot-drawing scenario but Seol Ki-hyeon, the striker who is keen to leave Wolves as soon as possible, insisted no-one in the Korea camp was thinking about what might happen elsewhere.

He said: "We are not thinking about the France game at all. We just want to win our game and we need to win it.

"Switzerland are a very good team that is very physical and well-organised but we know their players very well. We are going to do our best to get the result we need."

It will be 4am in Korea when the match kicks off but nonetheless a million people are expected to leave their homes and watch it on big screens across the nation, with 250,000 expected to gather in the main square of the capital, Seoul.

South Korea Football Association Chung Moon Joon, who is also a FIFA vice-president and a member of the family that owns the Hyundai company, was confident of victory.

He said: "We have no serious injuries, which is good news, and the players are fully motivated and full of confidence. Victory would mean a lot to the people of South Korea.

"Korea is now one of the world's strong footballing countries and will continue to prove that in this game."
