"This is a man with nothing else to prove, who's the greatest sprinter of all time. He's been hurt, has every excuse to lose motivation, get distracted, and fade. And yet he summons, on command, breathtaking performances time and time again."Time's Sean Gregory.
"Usain Bolt produced perhaps his greatest performance of all as he put a troubled build-up behind him to beat two-time doper and clear favourite Justin Gatlin to retain his world 100m title." Tom Fordyce, chief BBC sports writer.
"For those who had painted this battle as a nothing less than clash of good against evil in light of the doping issues that have left his sport on life support, Bolt's victory in the Bird's Nest stadium where he made his name may have even secured its future." Owen Gibson, in the Guardian.
