Both Pele and Maradona led their countries to the top of international soccer during their careers, and Messi's performances for his country have been severely disappointing. While he was still a teenager in 2006 --and his lackluster showing is excusable due to his youth--he cannot brush off the disappointment that characterized Argentina's performance in 2010. But the 4-0 loss to Germany in the 2010 World Cup Quarter Final seems to have sparked Messi. He scored 12 times for Argentina last year, and the next World Cup could finally be Messi's breakout performance in blue and white stripes. Due to all of his accomplishments, it is easy to forget that the extraordinary footballer is just 25 years old.
