To be classed as a great heavyweight boxer it is often said that a fighter needs to duel with the best combatants of his time. George Foreman, who has died aged 76, unquestionably did that, having had epic world heavyweight title rivalries in the 1970s with Muhammad Ali and Joe Frazier, beating the latter to win the world heavyweight title in 1973.
However, in some ways his more deserving claim to greatness was an astonishing comeback that saw him become the oldest world heavyweight champion two decades later.
