Because that is what can be said about the Danish team: they fight with spirit, are well-organised, and cold-blooded in the important situations - they follow their luck, and thus are deserved winners of the group.
That said, the Danish team still lacks stars, and when they play bad (like they did tonight, or recently against Albania), they play awfully, something that they can ill-afford in South Africa. However, one of the main reasons they have qualified is that they have been favoured by hugely disappointing opponents in the qualifiers: Portugal is surely a better team than Denmark, but have as usual been arrogant and lacked a fighting spirit that can still cost them their qualification in their coming play-off match.I am sorry for Sweden, but they have simply been awful, and I really think that this must be the worse team in Swedish history; the players are not that bad, but they play primitively and predictable football, with high balls up to Ibrahimovic, who in spite of his stardom in his clubs, seems to be no particular asset when the tactics are so predictable. Sweden will not be missed in South Africa.
Anyway, Denmark will not be world champions. Depending on the draw, they may struggle to progress from the first round, but on the other hand, the comforting thought for a Danish fan is that the Danes seem to perform best when faced against outstanding opponents, but disappoint against smaller teams. I certainly hope it is the former that they will take with them to South Africa!
