Justin Gatlin stunned the world to claim the 100m World Championship title and leave Usain Bolt trailing in third place in his final individual race before retirement.
Despite a low-key season, Bolt was expected to claim a fourth 100m World Championship title but instead was left with a bronze medal, that will sit alongside his 2011 disqualification in Daegu rather than the jaw-dropping 9.58 world record of his 2009 success.
Instead it was the controversial Gatlin, twice banned for doping offences, who claimed a second World Championship title, 12 years after his only other 100m World Championship gold in Helsinki to go with his 2004 Olympic title.
