With the World Championships in Beijing a month away, Usain Bolt displayed his customary confidence in front of a packed media conference.
Usain Bolt was in bullish mood on Thursday, as he looked ahead to the IAAF Diamond League meeting in London and the upcoming World Championships in Beijing.
The six-time Olympic gold medallist has struggled for his best form in 2015, with American rival Justin Gatlin continuing to post fast times in both the 100metres and 200m.
With the Worlds in China just a month away, Bolt - still the world record holder over both sprint distances - maintained his air of supreme confidence ahead of this weekend's Diamond League event.
"I never doubt myself," said Bolt, who took 100m and 200m gold at the last Worlds in Moscow two years ago, with Gatlin claiming silver in the former.
"Beijing is a month away. I've been training hard and pushing myself.
"The first 40 metres is my most important part, if I get that right I know I have no issues.
"I need to run more 100 metres now, this is what I've been focused on. For me, it just takes one run to get to 9.7 [seconds].
"I'm not planning on losing in Beijing."
The Jamaican is relishing a return to the city where he won three Olympic golds in 2012.
"The Olympic Games was epic, I'm looking forward to competing [in London] again," he said.
"London is one of the most memorable stadiums to run in for me. I really enjoyed running there during the Olympics.
"I come here for the fans, they support me and I want to do great for them. I want to put on a show."
