Four-division world champion and Mexican boxing legend Juan Manuel Marquez, still regarded by many boxing experts as one of the best pound for pound boxers in the game, celebrated his 40th birthday today.

The Mexico City-born Marquez is currently training for his attempt to win a world title in a fifth weight division against WBO welterweight world champion Timothy Bradley on October 12 in Las Vegas.
