Everyone in the world is preparing for the fight of the century, as Floyd Mayweather will take on Manny Pacquiao on May 2 in Las Vegas. In the press conference Wednesday, cameras caught up with former boxer Mike Tyson to get his take on the bout.

He did not hold back.

Tyson went off about Mayweather's recent claim that he is better than Muhammad Ali:

He's very delusional. Listen, if he was anywhere near that realm of greatness with Ali he'd be able to take his kids to school by himself. 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, greatness is being accepted by the people. He can’t take his kids alone to school by himself.

Iron Mike finished with a knockout line.

"He's a little, scared man. He's a very small, scared man," Tyson said as he walked away.

Update: Friday, May 1, 2:24 p.m. ET

Tyson took to his Instagram to speak on his previous claims. It should be noted, however, that he is not just referring to his "small, scared man" comments but a Boxing Junkie article about a police raid.

The caption reads as follows:

An article circulated today, which referenced an incident that happened to me many years ago. It was released without my consent or endorsement. It inferred that I had animosity towards Floyd Mayweather Jr. because of something that happened many years ago. This entire article is speculation and it’s unfortunate that it would be released at all, especially the day before the biggest fight in decades. I have no ill will towards Mayweather and have a great deal of respect for his discipline in and out of the ring. He's proven he is one of the greatest athletes of all time and will go down in history as such. Things got blown out of proportion when I was interviewed the other day about a comment Mayweather made stating he was greater than Ali. I disagree and personally found it insulting because of the love and admiration I have for Muhammad Ali. I thought it was inappropriate to make that kind of reference especially because Ali has done so much, not just in the sport of boxing but for humanity as a whole. In retrospect, I wish I had exercised better discernment in my response because in no way did I want to disrespect Mayweather. The focus should be on the May 2nd bout and the great economic surge this event is generating for the city of Las Vegas. I sincerely wish Floyd Mayweather Jr. and Manny Pacquiao the best of luck on Saturday night’s historical event.

It all goes down this Saturday.
