MIKE TYSON could knock out Deontay Wilder in 60 seconds, his coach once claimed ahead of the Bronze Bomber's latest title fight.
Wilder, 35, takes on Tyson Fury next week in a bid to win back his WBC heavyweight belt.
But his trilogy of match-ups with the Gypsy King have failed to impress some boxing commentators, including Jeff Fenech.
The Aussie trained Tyson, 55, ahead of his comeback showdown with Roy Jones Jr.
He told Sporting News: "I'd guarantee that if Mike Tyson trained for six weeks, he'd knock Wilder out in a minute.
"He would hit them. If these guys are getting knocked out by Tyson Fury - who's a great fighter, but not a huge puncher - Tyson would kill these guys.
"They're not on the same level today.

"Mike today, I reckon if he trained he could still beat these guys."
As one of the ring's all-time greats, Tyson has never been afraid of comparing himself to the sport's current champions.
The American recently declared his prime self to be comfortably better than Anthony Joshua and Oleksandr Usyk following their title fight.
Next up for Tyson could be a showdown against fellow former champ Lennox Lewis, which was talked up by the legend instead of a rematch with Evander Holyfield.
Tyson told ESNews: "I want a fight. I need another one.
"We were supposed to go with Evander Holyfield but Evander f***ed up the money so we got to do it with Lennox now."
