Both Liddell and Tyson dominated their respective combat sports during their prime. Liddell reigned over UFC's storied light-heavyweight division while Tyson ruled boxing's heavyweight division.
But what would happen if they were to brawl in the streets?
Well, Liddell fancies his chances of beating Tyson in a street fight.
"In a street fight, I'd win," Liddell said. "I mean, he's got a puncher's chance. He's got a chance to catch me coming in. But other than that, it's over."
The 50-year-old scored some devastating knockouts inside the Octagon, from thrashing Tito Ortiz to stopping Randy Couture.
He fought as recently as November 2018, where he was knocked out by Ortiz under the Golden Boy MMA banner.
He announced back in March in an interview with TMZ that he was calling time on his MMA career once again.
Tyson, on the other hand, was crowned boxing's undisputed heavyweight champion back in 1987 at the age of 20, before retiring in 2005 after losing to Kevin McBride.
And in an interview with GQ, the 54-year-old said he could never have become a UFC superstar.
"I don't know what I would do in the UFC, because I watched the UFC a couple of times, and I watched these guys step on people's feet," he hilariously explained.
"And I have the worst feet in the world, and if somebody stepped on my feet, I would totally tap out and just give up.
"It would be a no-brainer."
