You can’t really call it an upset when the #10 team in the world beats somebody, but this was a surprise result. The Dutch did outshoot the Danes, Robben did hit a post and Huntelaar was denied what should have been a penalty for a Danish handball late in the game, but the Dutch didn’t really play like potential champions. Sneijder did his part (his outside of the right foot 40 yard pass to hit Huntelaar in stride in the penalty box was sheer class), but van Persie and Robben were off color and the coach should have brought van der Vaart and Huntelaar on earlier. Nonetheless, it was a great win for Denmark and Kjaer, Poulsen and Agger did very well.
This result means that, assuming Germany performs as expected, the second team to go through in this group will be determined by how many points each of them can win off of Germany. Head to head performances are the first tie breaker prior to checking on goal difference. So, if we assume Germany beats Portugal next, Portugal beats Denmark in the second round and Netherlands beats Portugal in the last match – those are a lot of assumptions – all the teams will have a chance to go through if they can get at least 1 point off of Germany. This group is thoroughly in flux and could be even more so if Portugal beats Germany shortly.
