Marcell Jacobs won the first Olympics title in the post-Usain Bolt era, crossing the line in a new European record time of 9.80sec ahead of the United States' Fred Kerley and Canada's Andre de Grasse.

The men's 100M, the first at the Games not featuring three-time champion Bolt since 2004, had been difficult to predict and that continued in the semifinals as favourite Trayvon Bromel of the USA failed to qualify.

The quickest times were in the third semi-final, won by 60M expert Su Bingtian, who smashed the Asian record with a time of 9.83 to become the first man from the continent to reach the Olympic 100m final since 1932.

After Great Britain's Zharnel Hughes was disqualified for a false start, Su this time could not get the explosive start he needed and it was Jacobs who held his form and speed to cross the line first.

"It's amazing, fantastic, it's a dream. It's incredible. No words," Jacobs told BBC.

Tamberi added, "This night is memorable. We made our dream come true and we passed through many difficult times."
