Usain Bolt is disappointed with how Jamaican men's sprinting has developed since he retired and predicts his compatriots will find it tough in Tokyo after his glorious domination of the last three Olympics.
With Bolt leading the way in his own inimitable style, Jamaica won all nine men's track sprint finals in Beijing, London and Rio — although they later lost their 2008 4x100-meter gold medals after Nesta Carter failed a drug test.
While Jamaica's women look very strong going into their Tokyo campaign, triple 100-meter and 200-meter Olympic champion Bolt thinks the men will struggle.
