- London Olympics 2012
Bolt not concerned by Blake threat
Blake won the world 100m crown in Daegu last year after Bolt was disqualified for a false start in the final.
World record holder Bolt ran a world-leading time of 9.76 seconds in Rome last month, while Blake, who has clocked 9.84s this year, has already warned he has no interest in a silver medal in London.
"Everybody wants to be that No. 1 person. They don't want to be that second guy," Blake said recently.
But despite surrendering his world 100m title to his compatriot in Korea, Bolt is confident he has the natural pace to see off Blake. The pair will go head-to-head at the Jamaican trials.
"Yohan really wants to beat me at the Olympics so he's really pushing himself," Bolt said, "I'm not worried, I know what I'm capable of. I know what I can do so all I have to do is go out there and do it."
