Olympic Champion Usain Bolt has said that he is even more focused than last time to get the world championships title in Moscow and the absence of some of his main rivals would not make him drop his guard.
According to stuff.co.nz, American Tyson Gay and Jamaican former world record holder Asafa Powell will not compete in Moscow after failing doping tests and Jamaican Yohan Blake will not defend his title because of a hamstring injury.
Bolt, who retained his Olympic title last year, said after arriving in Moscow for the world championships that he was not worried he would repeat the nightmare of Daegu in 2011, when he was disqualified for a false start, the report said.
He expressed that he would not jump the gun by discussing the doping tests failed by Powell and Gay, because the full details were not known, the report added.
