Claressa Shields is still just 27-years-old yet her place in boxing history is assured.
A decade ago she was one of the first three women to win gold medals for boxing at an Olympic Games. At Rio 2016 Shields became the first American boxer to become a two-time Olympic champion.
She cut a swathe through the professional sport, winning world titles at multiple weights, culminating in her victory over Savannah Marshall at the O2 Arena in London to become an undisputed champion for the third time.
