  • Up next ... Chad le Clos

    The South African swimmer came to the world's attention in 2012 when he beat the mighty Michael Phelps in the 200m butterfly at the London Olympics. He has since gone on to more glory picking up six golds at the short and long-course World Championships in Spain and Qatar over the past two seasons. Still only 22 years old, le Clos is set to become one of the greatest swimmers of all-time.
