Striker Nicklas Bendtner is sure that Denmark's height advantage will prove to be pivotal when face Japan in their World Cup Group E encounter in Rustenburg on Thursday.
The Danes lost 2-0 to Holland in their opener but beat Cameroon 2-1 on Saturday to knock the Africans out of contention with the Arsenal striker on target for Morten Olsen's side.
Denmark will go into the game against an improving Japanese defence knowing that only a victory would take them through as the Asian outfit hold a superior goal difference.
"Japan is a good team and very defensive, but I believe in the strength we have," said Bendtner.
"I would be bitterly disappointed if we didn't win."
The 22-year-old added: "We know we have to score. But if we can hold the ball up and use the height we have in attack then I believe that could break any defence down."
Japan have conceded only one goal so far in Group E when Wesley Sneijder scored the winner for the Dutch to edge them in Durban but they did upset Cameroon 1-0 earlier in their opener.
Coach Morten Olsen believes it would have been better if the Danes only required a draw against Japan, but the 50-year-old is sure his side have the ability to dispose of their opponents and secure a place in the last 16.
"Of course it could be better that we only had to have one point (against Japan) but that is the situation. The reality is we have to win the game," he said.
