1: Floyd Mayweather
Love him, loathe him, but never dispute his natural talent.
Mayweather's credentials are endorsed by a rich history which dates back to long before he ever stepped onto the professional scene.
As a young amateur Mayweather boasted a record of 84-6 and was soon dubbed 'Pretty Boy' due to his immaculate defence. Of course the American's professional career has been even better, and he now sits with a record of 45-0.
Perfection through hard work may be his mantra, but that's impossible without a high level of natural prowess to win fights.
