Spain have been the best team in Europe for the last two years, ever since the conclusion of the 2006 World Cup. This was a just reward for them for their success (22 matches unbeaten now) since the onset of Euro 2008 qualifying. I'd like to see what the odds on them are right now for the 2010 World Cup.
I'm not sure I would bet on them winning the 2010 World Cup. First, its two years away. A lot can happen in that time.
Second, they won Euro 2008, but it isn't as if they won it in overwhelmingly convincing fashion. Not to take anything away from the accomplishment at all but PKs vs. Italy and a 1-0 (with the winner in the 33 minute) over a German team that has been giving away goals easier than a prom date's virginity just isn't all that convincing to me.
Third, Aragones is gone.
Fourth, look at some of the players who either won't be around or will be pushing it age wise, I'll just list the guys who will be 30 or over. Puyol will be 32, Marchena will be 31, Capdevila will be 32, Juanito certainly won't be there (not that it matters a whole lot), Xavi Hernández will be 30, Senna (probably won't be there) will be 34, Güiza will be 30. Now I'm not saying a guy can't play after 30, I'm just saying....
Fifth, up until Euro 2008, who was Spain's competition in those 22 unbeaten matches? They've had some friendlies they've won 1-0 over some decent competition but for meaningful competition its been powerhouses like Northern Ireland, Liechtenstein, Latvia, Iceland and other mighty footballing nations.
Anyway, those are just a few reasons I don't see this as a sign that Spain will win a World Cup in 2010. I would bet on a European team winning the World Cup in 2010, but I don't see it being Spain.
