Spain - Argentina - what a spectacle!
In terms of player lineup and the quality of the game, they are among the main favorites for the 2010 World Cup in South Africa, although there is a possibility that the team's non-playing lineup, including the coach, might not be optimal. While Spain seems to be managing this well, I believe Argentina still has a problem in this area.
Friendly match
I didn't watch Brazil - England, but I assume that the match was less aesthetically pleasing.
P.S. Russia and France, in my opinion, will confirm their advantage, and Ukraine and Bosnia should settle the score in the return match... at least, that's how I'll be rooting for them.
