South Korean coach Guus Hiddink has angrily rejected suggestions the World Cup co-hosts are being aided by a conspiracy.

Hiddink continued: "Germany are a smart team and a team that needs only one or two chances to bring them victory."

Goalkeeper Lee Woon-Jae is also in bullish mood.
"Their shots and headers are really powerful but it will be easy for me to defend against this kind of attack."
