Following a successful career which saw him become the only sprinter to win Olympic 100m and 200m titles at three consecutive Games, Usain trained to become a professional footballer.
However, not long after – in January 2019, he announced he was stepping back from the sport.
At the time he said: “It was fun while it lasted,” before adding: “The sports life is over, so I’m now moving into different businesses.”
