Now the captain of the Argentina national team Lionel Messi is one of the all-time greats for both his club and his country. Nicknamed the Flea, Messi is fast on his feet and imposing on the soccer field, earning himself the third consecutive player of the year, or FIFA Ballon d''Or award, while playing forward for FC Barcelona and Argentina''s national team.

Five league championships, three Champions League titles and an Olympic Gold Medal are only the beginning of his accomplishments. He is a three time world player of the year and the all-time leading scorer for the world famous FC Barcelona. The 2011-2012 season saw Messi break soccer legend Gerd Muller''s single season record for most goals scored.
