Four years ago maybe we thought we were inferior to Brazil, subconsciously we didn't see ourselves beating them. Now we believe in ourselves, we can be on the pitch with any team in the world and think we can win.
I've spent my entire adult life with the United States as a superpower and one that had no compunction about spending what it took to sustain that position. And it didn't have to look over its shoulder because our economy was so strong.
