New world 100m champion Yohan Blake has vowed to show Jamaican rival Asafa Powell his true worth during tomorrow's Diamond League finals meeting in Zurich.
Prior to Blake claiming gold in South Korea, Powell described the 21-year-old as a "boy".
Blake has now responded: "He called me a boy but I'm running like a big man. It will be interesting [in Zurich]," he told BBC Sport.
Powell failed to compete during the World Athletics Championships because of a hip injury.
