Winger Michael Kronh-Dehli struck a first-half goal to give Denmark a shock victory over the Netherlands in Kharkiv.
The 29-year-old fired home against the run of play after collecting Simon Poulsen’s deflected shot.
The Dutch had plenty of opportunities, with Arjen Robben hitting the post in the first half while Arsenal’s Robin van Persie also went close.
After the break, Klaas-Jan Huntelaar had a superb chance but found Denmark goalkeeper Stephan Andersen in fine form.
The Danes then survived a late penalty appeal as they hung on to secure an unexpected victory.
The match ended with Holland having had a total of 29 shots, however only 6 of these were on target. Van Persie had a particularly poor performance for the Dutch squad, fluffing several chances for the wasteful side.
In the Netherland’s midfield Sneijder was the stand out player, he controlled the games tempo for the majority of the match, whilst displaying his passing ability with several delicious balls into Denmark’s penalty area.
Germany opened up their campaign with a hard-fought victory over Portugal courtesy of a second-half winner from striker Mario Gomez.
The 26-year-old headed back across the goal into the bottom corner from Sami Khedira’s deflected cross to put Germany ahead with only 17 minutes to go.
Portugal, who hit the woodwork in the first half, had struggled to break down a stubborn and well-drilled Germany defence but they piled on the pressure as they searched for an equaliser.
Manchester United winger Nani hit the top of the bar with a cross while Silvestre Varela had a late shot saved when there was only goalkeeper Manuel Neuer to beat.
