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 4x100m gold medals after Nesta Carter failed a dope test.
