When Muhammad Ali and Mike Tyson talked who would win a fight in their primes – ‘I don’t know what would have happened if he hit me!’

Muhammad Ali is often considered the greatest heavyweight boxer of all-time, but the legend himself once debated whether he would have been able to withstand Mike Tyson’s power.

Back in 1989 on the Arsenio Hall show, both Ali and Tyson - along with Sugar Ray Leonard - shared the sofa with the late night host and the question was asked: Who would have won if they fought each other in their primes?

“I was the dancing master and I wasn’t that powerful,” Ali began. “But I was so fast. If he hit me… [falls asleep]. [But] that’s if he catches me.”

Tyson, who has always maintained Ali is a hero of his, stayed humble and gave all praise to 'The Greatest'.

'Iron Mike' asserted: “I’m vain [laughs], I know I’m great, but can I tell you something? In this situation, every head must bow, every tongue must confess: This [Ali] is the greatest of all time.
