National soccer coach Dick Advocaat has pledged that South Korea will upset France in their second World Cup game Sunday.

Advocaat on Thursday said the game is important for both teams but that South Korea will stun the world by beating favored France.

France coach Raymond Domenech, meanwhile, said his team will improve its decisiveness to beat South Korea and restore confidence.

He praised South Korean players for their strong attack and agility, saying creativity in scoring goals will determine the outcome of what will likely be a tough game.
