Olympic legend Carl Lewis has told Usain Bolt which of his world records are at risk of being broken.
Bolt called time on his iconic sprint career in 2017 following a haul of medals, including an impressive eight Olympic gold medals.
He medalled in London, Beijing and Rio de de Janeiro, but secured his world records at the World Athletics Championships.
At the 2009 World Athletics Championships in Berlin, Bolt recorded a stunning time of 9.58 seconds in the 100m and clocked 19.19 seconds in the 200m.

Despite the 39-year-old walking away from the track almost 10 years ago, both world records are still intact.
Lewis, who won gold in the 100m at the 1984 and 1988 Olympics, believes Bolt's 100m world record will remain safe for a long time.

However, the nine-time Olympic medalist believes competitors have a 'better shot' at breaking the Jamaican's 200m world record.

"Well, I don't think it's going to be, anyone can break it anytime soon, no I don't, I just don't, I don't think right now (anyone can break the 100m world record of 9.58 seconds)," he said.
"There's probably a better shot at that (200m world record of 19.19 seconds), I definitely think it's a better shot at that, but I think the 100s is away for a while."
Carl Lewis says doping cheats need to be hit hard
The use of performance-enhancing drugs has been rife in the sport, with the likes of Justin Gatlin, Tyson Gay and Yohan Blake being sanctioned for doping.

And Lewis believes doping cheats should be impacted financially to deter sprinters using PEDs.
"To me, they (dope testing authorities) should go after you (dope cheats) financially. And they're like, how can you do that? Well, unless you reimburse, pay a fine, whatever, you can't come back (from the ban)," he explained.
"And maybe that ends your (dope cheats) career. That's on you (dope cheats)," added Lewis, who was awarded an Olympic gold medal in the 100m after Ben Johnson was stripped of the top position for testing positive for a banned substance.

Lewis reckons relentless testing is the only way to rid athletics of drug cheats.
He said: "The vast majority of people are clean and do the right thing. But I think until there's forever fear, we're not going to have it (a dope-free environment)."
