Usain Bolt lit up the Luzhniki Stadium by blazing to 100 metres gold at the World Championships in Moscow.
The world record holder defied the pouring rain to storm to victory on a drenched track in a revised time of 9.77 seconds, his best time of the year.
He held off the challenge of American Justin Gatlin, who clocked 9.85secs, with Bolt's fellow Jamaican Nesta Carter getting bronze in 9.95s.
Great Britain's big hope James Dasaolu was eighth in 10.21.
Mo Farah is hailed as Britain's greatest ever athlete after repeating his Olympic success with a double victory at the World Championships.
He won two Olympic gold medals last year and has already won gold this year in the 10,000 metres but is he the greatest of all time?
