10. Julio Cesar Chavez
One of the greatest Mexican boxers of all time, and that’s saying something!
OK, Chavez didn’t hang around too long at lightweight, but he was possibly at his mercurial best at nine-and-a-half stone.
Chavez was undefeated in 56 fights when he took the crown from Edwin Rosario in 1987, and defended three times.
He was first beaten in his 91st fight and holds the record for the largest crowd at a boxing match – 132,274 people crammed into Mexico’s Estadio Azteca to watch their hero beat Greg Haugen.
