They're the best team I've ever seen play. I'm 37 so I'm not old enough to know how good some of the former generational greats were, but for me, this Spanish run is the best I've seen. They have been fortunate to win a few penalty shootouts in the process, but never the less, they're quality across the board. A real spoil of riches on that roster.
One thing that soured me a little bit, was the push to score so late in the game, when Italy was down to 10 men due to injury. Screamed of trying to steal a base in baseball when you're up 10 runs, or throwing the football late in the 4th quarter, when the game is well in hand. Ultimately it's you're job to stop the other team, but at that point of the game I thought going for a 4th, then a 5th goal near time, was a bit much. (of course my personal feelings might be cause here )
Like one of you mentioned, this team, or country, isn't going to slow its dominance anytime soon. The players currently excelling are all in their primes for the most part, and the youngsters coming up are of exceptional quality as well. Truly Spain will be an international force for a long time.
