built one of the most remarkable and enduring careers in the sport, winning Olympic gold in 1968 and claiming the world heavyweight title twice, 21 years apart - the second making him the oldest champion in history aged 45.

He lost his first title to Muhammad Ali in their famous Rumble in the Jungle fight in 1974. But overall, he boasted an astonishing total of 76 wins including 68 knockouts, almost double that of Ali. Foreman retired in 1997 but not before he agreed to put his name to a best-selling grill - a decision that went on to bring him fortunes that dwarfed his boxing earnings. (BBC/Getty Images)
