Usain Bolt believes Cristiano Ronaldo is "definitely" quicker than him, and has hailed the Juventus and Portugal superstar as a "super athlete".
Bolt retired from athletics in 2017 but the eight-time Olympic gold medallist still holds the world records over 100 and 200 metres.
The 34-year-old clocked a world-record time of 9.58 seconds in the 100m at the 2009 World Championships in Berlin, while he also ran 200m in 19.19s 11 years ago in the German city.
But Bolt feels five-time Ballon d'Or winner and footballer Ronaldo is now faster, given the fact he is still delivering the goods week in, week out at the very highest level.
