MIKE TYSON once slammed Floyd Mayweather as “very delusional” for rating himself above Muhammad Ali.

Mayweather has always insisted he is “The Best Ever” and not even Ali, dubbed “The Greatest”, compares to his unbeaten run stretching over 50 wins and 12 world titles.

But Iron Mike slammed the former pound-for-pound king, and mocked him for taking his children to school accompanied by bodyguards.

Tyson said in 2015: “He’s very delusional.

“Listen, if he was anywhere near that realm of great as Muhammad Ali, he’d be able to take his kids to school by himself.

“OK, he can’t take his kids to school by himself, and he’s talking about he’s great?

“Greatness is not guarding yourself from the people. ‘It’s being accepted by the people.

“He can’t take his kids alone to school by himself. He’s a little scared man. He’s a very small, scared man.”

Tyson once revealed his fantasy fight would have been to share the ring with Mayweather, despite their weight difference separating them.

And even the youngest heavyweight champion of all time admitted Mayweather’s boxing skill is so unparalleled he would have to use dirty tactics to beat him

He told the Wall Street Journal: “We can never fight, of course, because of the weight difference, but I wouldn’t fight him the way they fought him.

“I would be mean, I would be dirty. Because you’d have to do everything to fight him because he’s just so good.

“It’s impossible to fight him clean. It’s almost impossible to fight him clean. You can’t fight him clean. You can’t fight this guy clean.”
