"We had a very strong team in 2010. But there were many injuries, [they] were not well prepared and now we are 100 percent ready, we are hungry for tomorrow's game... Many of our players don't have a clue of what it feels like to play at the World Cup, but they are used to the pressure, they are good players. We are united and tomorrow we will be united [as well]. No need to worry about our game," Kjaer told journalists.

Denmark will play their first World Cup match against Peru at the 42,000-seater Mordovia Arena in Saransk on Saturday before taking on 1998 champions France and Australia.
