Former British javelin Olympian Steve Backley has backed Usain Bolt to break his own world record during tonight's final of the men's 200m at the Games in London.
Bolt set the record of 19.19s during the 2009 World Championships in Berlin.
Despite some pundits questioning the 25-year-old's fitness, Backley believes that he is the right shape to set a fast time, as well as pipping his compatriot Yohan Blake to the title.
"I do not think it is at all out of the question that he will run a world record in the 200m, and he will break his own mark with Blake in a close second," he told Eurosport.
"I am predicting that it will be a quick, quick, quick race with Bolt just pipping Blake and setting a new mark for the 200m, which is, as we all know, his favourite event."
Bolt heads into this evening's race as the defending champion from Beijing.
