Trainer urges Powell and Simpson to come clean about doping
Chris Xuereb rejects blame for failed drugs tests of sprinters Powell and Simpson, telling them to instead look in the mirror

The trainer for Asafa Powell and Sherone Simpson has insisted he didn't give the sprinters performance-enhancing drugs and says it's time for them to take "responsibility for their doping instead of looking around for a scapegoat".
The trainer, Chris Xuereb, said he had done nothing wrong since the Jamaicans hired him in May to provide massage therapy and nutritional help.
Powell, the former 100-metre world record holder, and Simpson, a three-time Olympic medallist, tested positive for the stimulant oxilofrine at the Jamaican championships last month.
Their agent, Paul Doyle, contends something in the new supplements the sprinters were taking caused it and "Chris is the one that provided those".
Xuereb said he was disappointed the athletes were blaming him for their violations.
