Japan manager Takeshi Okada admits their World Cup hopes hang on silencing Arsenal's Denmark striker Nicklas Bendtner.
Bendtner scored as the Danes knocked out Cameroon with a 2-1 win to set up a final group clash with Japan which has become a cup final for both teams.
The tall Arsenal striker has had a groin injury but Okada is expecting him to play and has been drilling his players on how to shut him down.
Okada said: "Bendtner will be the key man in their attack. They will fight under his lead."
