Remarkably, 54-year-old Lennox Lewis remains the last undisputed heavyweight champion of the world.
Boxing has been waiting for a unification fight ever since his victory over Evander Holyfield in 1999.
On Saturday, one of the biggest fights in a generation could potentially edge the division closer to finding Lewis’ successor.
Tyson Fury and Deontay Wilder meet again following their controversial draw – live on talkSPORT – with the WBC title on the line.
The other three belts belong to Anthony Joshua, who is desperate to set up a mega bout against the winner to finally crown a new heavyweight king.
When asked if the long wait for a new undisputed champion upsets him, Lewis jokes: “Not at all!
“I know some time it will happen. But it’s taken 20 years and it might take even longer, so I might have some time left.”
Reports on Friday suggest Fury’s camp want to set up a mega fight with Joshua later this year, which could unify the division if the ‘Gyspy King’ wins in Las Vegas.
But these reports have become white noise, to a large extent, following years of supposed negotiations between Joshua, Wilder, and Fury.
“They have to take responsibility,” Lewis told talkSPORT. “The promoter has to take more responsibility, and it depends on what you want.
“For me, undisputed was definitely one of my goals I wanted to reach and I told myself I had to.
“That’s why I fought all these guys, especially before I retired.”
Nonetheless, Lewis expects the second fight between Wilder and Fury to finally bring boxing closer to the fight everyone wants to see.
“We’re basically getting there,” he said. “With Wilder and Fury fighting, it’s ever so close because you’re talking about the two top guys in the division.
“They want to see themselves, who is the best boxer? It’s not only the world wants to see it, they want to see it as well.”
