Mike Tyson says against his upcoming boxing match Jake Paul is not just the greatest fight in the sport’s existence… it’s the “greatest fight in the history of life!!”

The boxing legend icon made the statement Harvey And Karel on “TMZ Live” on Tuesday … saying that despite all the blockbuster Pay-Per-Views he’s headlined over the years, Friday’s event at AT&T Stadium takes the cake.

The 58-year-old admitted this is the most hyped fight in the world, claiming: “(There’s) never been a fight this big.”

Iron Mike has been part of boxing’s most iconic matches… with opponents like Lennox Lewis, Evander Holyfield, Buster Douglas And Trevor Berbick over the course of his career.

But now he’s going up against a YouTuber turned fighter… and he told H&C that it’s not going to be a great night for El Gallo.

“On Friday night, they can look forward to seeing that man Jake Paul get severely beaten,” Tyson said. “My intention is to knock him out.”

The fight was initially scheduled for July 20th…but it was postponed to this weekend after mike a flare-up of the stomach ulcer.
