Jamaican sprinter Usain Bolt has admitted that he would love teammate Yohan Blake to triumph at the London Olympics if he doesn't win himself.

Blake appears to be the main threat to the world record holder's chances of winning both the 100m and 200m at the Games after beating him in both events at the Jamaican trials.

However, despite being in competition with one another, Bolt is hoping that his 22-year-old friend will have an impact at this summer's event.

"We train every day, I know how hard he works, so I would love for Blake to win if I wasn't in the 100m, but let's not ask this question again please, let's not jinx me on that one," Bolt said.

The men's 100m and 200m finals take place on August 5 and 9 respectively.
