The Roma man says Bert van Marwijk's side are determined to collect three points against their arch rivals, and admitted that they must pick up a win in order to have any chance of progressing to the quarter-finals.
"I'm very confident about the game,” the 29-year-old told the official UEFA website. "I could really sense it in training today. We'll do everything we can because we need a good result to stay in the tournament."
The former Ajax star believes his side must be cautious of the danger die Mannschaft pose on the break, but feels that his teammates pose just as much of a threat.
"I think we'll start the game the same way as against Denmark, but the danger is that Germany have great players to counterattack if we lose the ball. That's why we'll have to be very wary of blocking those attacks, because that's one of their strengths.”
"Germany has a very good team, with some great players, but so do we.”
