Boxing champion, Anthony Joshua is relishing the “great responsibility” of attempting to become the first man to hold all four heavyweight world titles.
The 28-year-old IBF and WBA champion faces Carlos Takam at Cardiff’s Principality Stadium on Saturday.
A win will fuel talk of unifying the titles with the WBC crown of Deontay Wilder and Joseph Parker’s WBO version.
“History is a great thing to chase,” Britain’s Joshua told BBC Sport. “It’s very possible and a great challenge.”
Asked if timing fights to satisfy all four sanctioning bodies made the task difficult, Joshua said, “We will find a way to make it happen.
“It’s like a diamond in the dirt, the treasure, trying to get that pot of gold at the end of the rainbow.
“If we can make it happen, I will be up for it, but if not, it’s not the end of the world and leaves a record to break for someone else.”
Mike Tyson held three heavyweight titles in 1987, before the formation of the WBO.
Since that body was created, no man has held four titles, with Evander Holyfield, Riddick Bowe, James ‘Buster’ Douglas, Lennox Lewis, Wladimir Klitschko and Tyson Fury all laying claim to three belts at once.
At Thursday’s final news conference before his meeting with Camroon-born French Takam, Joshua stressed he wants to put April’s Wembley victory over Klitschko behind him.
Takam insisted his speed would be key against Joshua.
“I’m not bothered about fighting in front of 80,000 people, the only people in the ring will be myself and Joshua, nothing else matters except the two athletes,” The Telegraph quoted the 36-year-old as saying.
“I don’t see people when I am in the ring. This is a huge opportunity for me and heavyweight boxing can change in a round. If I can do things differently from what other boxers have done against Joshua, I’ll have a chance to win by knockout.”
