Eight-time Olympic champion

Bolt's warning to rivals

The eight-time Olympic champion reminded his rivals that he remains the fastest man in the world, despite an underwhelming 10.03 seconds over 100 metres on home soil this month.

In the meantime Andre De Grasse - who took third in the 100m in Rio and silver in the 200m - clocked a wind-assisted 9.69secs in Stockholm to underline his growing threat to Bolt's supremacy, and long-time rival Justin Gatlin won the US trials last week.
