Jordan Burroughs: The 23-year-old that the United States are relying upon to end Russian dominance at London. New Jersey-born Burroughs became one of the youngest American world champions last year when he won the freestyle world crown at 74 kilograms. He is a wrestling product from the University of Nebraska. His Twitter account is @allIseeisgold.
Aleksandr Karelin: Nicknamed "Alexander the Great", Karelin started wrestling at 13 years old in Siberia and went on to win three successive Greco-Roman Olympic golds. Famous for the 'Karelin lift', which involved picking his opponent off the floor and slamming them into the mat, the huge Russian went 13 years unbeaten before retiring after defeat in the final at the Sydney Games.
Ara Abrahamian: Maybe not the biggest flop, but certainly one of the most shameful moments in the sport's Olympic history - Abrahamian won bronze but caused embarrassment for his native Sweden by throwing his medal to the ground while on the podium. The Swede was angry about the judging in his semi-final bout.
DID YOU KNOW?
Before the points system was introduced, bouts continued until one wrestler was forced to the ground. One bout at the 1912 Games in Stockholm lasted a world record 11 hours and 40 minutes. Martin Klein of Russia eventually beat Finland's Alfred Asikainen to win the Greco-Roman 75kg silver medal.
