World number one runner, Usain Bolt is officially the fastest person in the world, but according to a new report, that might not be true.
Arsenal sensational right-back Hector Bellerin has reportedly ran a faster time than the Jamaican sprinter.
The Spanish full-back has smashed Thierry Henry and Theo Walcott's sprint records at Arsenal and as he ran the fastest time 4.1 secs in a 40 metre sprint.
Bolt set his 100m world record back in 2009 at a ridiculous 9.59 secs and was officially timed going through 40m in 4.64 secs which is more time than Bellerin.
In a 100m race however it is obvious Bolt would beat Bellerin but at the 40m mark, Bellerin is king.
