I trust what I see. Italy got seriously lucky in the 2006 tournament. They played powerhouses such as Australia and the Ukraine in the elimination rounds. Had a very nice game against Germany. And needed penalties to beat a 10 man France.
They avoided most of the big clubs. I think you ask most astute soccer observers that Argentina was the best team at that tournament. But that doesn't necessarily mean you will win it. Once Pirlo was injured, I figured they would be done. He's the only class player on that team that has creativity abilities. Brazil winning in 2002 was great. A great team, won the right way and played wonderful football. Italy's 1982 win was nice. That was a nice side with Rossi.
I thank the football gods that teams such as the Dutch, Brazil (except this year), Argentina to mention a few teams are around to play the beautiful game.
As for Inter beating Barcelona, Inter were completely dominated in the return leg. Inter played the games of their lives and caught Barcelona in the first leg. There was also a Dani Alves penalty that was not allowed that was pretty clear. Off the top of my head, there were 4 Argentinian's on the Inter team. Two did not make the national team, and one is on the bench. Inter were pretty fortunate in the final that Ribery wasn't playing and that an Argentinian's quality came to the team's rescue and got them the victory.
By reading many of your comments, it's fairly apparent you have never played soccer at any level and watch Serie A and the World Cup and make yourself a resident expert to NFL fans.
I just skimmed this thread once in a while - but to answer someone's questions - yes, there are many tactical changes during the course of the game that occur. For the novice fan, what I would recommend looking at how players use space and attack space. Far too often a player is able to attack space and is in a dangerous attacking position but then will lay it off to the wing. Any defender will tell you - thanks. The players that are truly danger - Villa's, Messi', Ronaldo's are the players that attack the space, attack defenders. They force the issue. This scares defenders. This is why they are so successful. The use and creation of space is a beautiful thing when done right.
