USAIN BOLT

Despite coming into Rio with concerns over his fitness, the superstar crowd pleaser romped to a "triple triple" of gold in the 100m, 200m and 4x100m. The Jamaican also sealed his status as track and field's greatest showman, posing for numerous selfies while even trying his hand at javelin in an eerily quiet Olympic Stadium once the crowds had left. "There you go. I'm the greatest," said Bolt.

 

 

MICHAEL PHELPS

The US swimmer also had his doubters on the eve of Rio, but left with five more golds to take his total to a stunning 23. "I don't think you're going to see another Michael," said coach Bob Bowman. Phelps, watched by fiancee Nicole and baby son Boomer, ended his career with no regrets after flirting with retirement coming away from the London Games four years ago. "It definitely was a lot more emotional than I was in 2012," said the 31-year-old.

 

MO FARAH

Britain's Mo Farah, born in Somalia but nurtured in London, captured a "double double" of 5,000m and 10,000m golds to emulate Finland's Lasse Viren, who did the same double at the 1972 and 1976 Games. Farah, 33, last lost a race at a major competition when he was beaten by Ethiopia's Ibrahim Jeilan in the 10,000m at the 2011 world championships in Daegu, South Korea.

 

 

NOVAK DJOKOVIC

World tennis number one Djokovic, looking to complete a career 'Golden Slam' of Olympic gold and the four majors, was knocked out in the first round by a rejuvenated Juan Martin del Potro who went onto make the final. Djokovic left the arena in tears and at 29 years old, his Olympic haul remains a modest bronze from Beijing in 2008.

 

 

LEE CHONG WEI

Malaysia's Lee suffered a third consecutive badminton final defeat after China's Chen Long beat the world number one in straight games. "Today leaves me with some regrets," said Lee, putting on a brave face following his defeat to second-ranked Chen, who became Olympic champion for the first time. The Malaysian has never won a world or Olympic title and will retire without that elusive gold medal.

 

 

RENAUD LAVILLENIE

Defending champion and world record holder in pole vault, the Frenchman slumped to a shock loss to Brazilian Thiago Braz da Silva. He was booed when he competed and booed when he stood on the podium holding the consolation of a silver medal. He didn't help his case by comparing the Rio jeers to the treatment received by Jesse Owens at Hitler's 1936 Olympics in Berlin.
