Argentina's midfield is fine right now. Pastore didn't feature last night. Once he does, Argentina will have a stellar midfield. The defense looks a lot better. Most importantly, the attack is the best in the world.
No European nation is going to South America and winning the WC. You can bank on that. It's Argentina vs. Brazil for 2014.
Spain/Germany will surely be in there. Don't think the brazilians could keep up with them,the teams a lot weaker than it used to be but obviously the home support will be another factor as well.
