The World Youth Championship
Messi played in the U-20 World Cup in 2005 and proved that he was ready for the highest level. Argentina won the Championship with a victory over Nigeria in the final. Every country loves success but this was all about Messi. He was the shining light in a tournament that only diehard fans follow.

This was before he made his full international debut. He scored six goals in the competition and won the Player of the Tournament award. Stunningly, the Argentinian coach dropped him for their first game against the USA. But then he came back and proved his value to his nation (via Outlook India).
