Mike Tyson is unsure if he would get the better of world heavyweight champion Anthony Joshua.
The Brit will put his unbeaten record to the test when he faces Andy Ruiz Jr in New York next month.
Joshua currently holds three of the four major heavyweight belts and is hoping to emulate former undisputed champion Tyson, who unified the division at the age of 21.
Ahead of Joshua's fight with Ruiz Jr, Tyson was asked how he thinks he would get on against him.
"I really like him. You know what he is? He’s really a breath of fresh air," Tyson said on the Hotboxin' Podcast.

“He’s really clean, he really looks clean, he’s a clean guy, he’s a clean fighter, he’s a good puncher. You just wish the best for him.
“I don’t know. My ego says, ‘nobody would beat you’.
"He just looks beautiful! He just looks like a fighter, you know? He looks like he was born to do what he has to do.
“He needs more experience of course, but that will come in life.”

Meanwhile, Tyson has revealed how smoking toad venom has changed his life.
The American has faced problems away from the ring but says the hallucinogenic drug has mellowed him.
“I really don’t have much regret. My violence, my drug habits, my reckless sexual escapades, my street fights and car accidents, all that time is over and I am still here so now it is about making a better life for my family. I am grateful for existing and having another life," he said.
“Once I smoked it, everything went boom! When I came down my brain was functioning and I could talk but I was saying ‘I f***ed up’.'
