#3 Michael Phelps (USA)
When Michael Phelps had retired after the 2012 London Olympics, everybody thought it was the end of an era in which the American became the most decorated Olympian of all time. But Phelps stunned the entire sporting world, when in 2014 he announced that he will be coming out of retirement and start competing again.
He has since qualified for the Olympics after winning the 100m butterfly, 200m butterfly and 200m individual medley events at the US Trials last week.
The all-time best athlete at the Olympics will be competing at his fifth Olympics in Rio. He has previously won 22 medals at the Olympics – 18 gold, 2 silver and 2 bronze. He will be defending his 100m butterfly and 200m individual medley gold medals and should be competing all the three men’s relays at Rio 2016. He could snap up six more medals this time around.
