Qatar speedster vows to beat Bolt

Asian 100m champion Femi Ogunode says he will outsprint Usain Bolt at the 2016 Olympics in Rio de Janeiro - even without the aid of a coach.

The Nigerian-born runner took the gold medal for his adopted country Qatar with a continental record of 9.93 seconds at the Asian Games in Incheon, South Korea, on Sunday.

Ogunode, 23, clocked the fifth-fastest time in the world this year despite dispensing with his coach four months ago and opting not to replace him.
