They play different sports and basically, it is not fair to compare an athletic who simply runs at his fastest pace without barrier, opponent or exhaustion time before with the football player who has different other things to do than simply racing.
Between running by dribbling the ball or running on the track is a different thing in my opinion, in this case besides having to run fast, of course Ronaldo must also concentrate on the ball and it's different from what was done by Usain Bolt who only focused on running as fast as possible ;DHowever, from some existing data it shows that Ronaldo can be as fast as Bolt and that has been acknowledged by after Bolt himself in several interviews in the media.
Bolt currently has a world record of 9.58 seconds for the 100 meter run, and this record was obtained at the World Athletics Championships in Berlin in 2009 and so far no runner has been able to break it.
while Ronaldo has a record of running 10 seconds for a distance of 92 meters at a speed of 33.12 km / h when Juventus against Napoli in September 2019.
So, in my opinion, these two athletes have speeds above the average in their respective fields compared to other athletes.
