Netherlands defender Johnny Heitinga says nothing short of victory will do against Germany on Wednesday.
"It is going to be a battle but we have to show that we can become champions," said the Everton centre-back.
"We have to win now, there's no excuse, and we are aware of that. We know we have to win against the Germans."
The Dutch were guilty of wasting a number of chances against Denmark and the 2010 World Cup losing finalists risk being knocked out of the competition in the group stages if they lose to Germany.
In competitive matches, Germany have three wins compared to two for Netherlands, while four have been drawn.
"You simply have to beat Germany, that is clear," said Netherlands coach Bert Van Marwijk. "And I refuse to accept defeat at this stage.
"We showed we can play well. We can create a lot of chances. We also showed that. And in the past we have proven that we can beat Germany, so why not now?"
There is an uneasy history in fixtures between the two countries and Germany coach Joachim Loew was hoping for a draw between the Dutch and Denmark.
"I would have preferred it if they [Netherlands] had drawn [against Denmark], a strong Holland team has to win now," said Loew, who is also wary as Germany lost their second group games at the 2006 World Cup and at Euro 2008.
"The Dutch had a huge amount of chances, I am surprised they didn't score a goal, it is all or nothing for them now.
"It will make it all the more difficult, but exciting, for us."
Germany won 3-0 in a friendly against Netherlands last November, although ex-Germany international and team manager Oliver Bierhoff says too much cannot be read into that game.
"We should not see that game as a standard," he said. "We would be crazy to think that this game will be anything like that. It will be a much more physical game.
"They were missing two or three players then. Now it will be a much tougher game because they are under pressure to win.
"But if everything comes together for us we can win this game. We have said we want to beat the Dutch and that has not changed."
