"Almost perfect, but we'll work on it," Francis said when he greeted Thompson-Herah in the halls of the Tokyo Olympic Stadium. Thompson-Herah led a Jamaican clean sweep of the medals, with Shelly-Ann Fraser-Pryce finishing second in 10.74, while Shericka Jackson claimed bronze in a career-best 10.76. When asked why the performance was not perfect, Francis told the Jamaica Gleaner: "Not the time, but the execution. Thompson-Herah's Olympic record time has been beaten only by Florence Griffith-Joyner's 1988 world record of 10.49 - though the American also ran a 10.61. Francis previously coached Fraser-Pryce to back-to-back Olympic 100m titles in 2008 and 2012 as well as a number of titles at the world championships.
