Win or lose against his domestic rival, WBC champion Tyson Fury would view himself as the best heavyweight fighter of this era.
Fury's handlers are attempting to finalize a full division unification with WBO, WBA, IBF, IBO champion Anthony Joshua.
The two boxers have agreed to take part in a two-fight series. And the first encounter is only missing a concrete date and location - which both sides are currently working on.
Fury, undefeated in 31 fights, shocked the world in 2015 when he traveled to Germany and handed Wladimir Klitschko his first defeat in over a decade.
Fury would not fight again until mid-2018 - as he battled depression and substance abuse issues.
Because all of Fury's belts became vacant, it allowed Joshua to capture his current titles with fights against Klitschko, Charles Martin and Joseph Parker.
Last year, Fury made another statement when he stopped Deontay Wilder in seven rounds to capture the WBC world title.
“When I win I am the best of this era because I beat everyone in it. Klitschko, Wilder and AJ. If AJ wins he will still not have beaten anybody. He has to beat me and Wilder," Fury told Behind The Gloves.
“I don’t think he can beat Deontay Wilder, I have no love for Wilder, I think he is a piece of sh!t dosser but I am the only man who can beat him. I am not a betting man but I would put a lot of money on Wilder beating all the others, including Joshua.
"I have helped [Joshua] become a superstar. He only has his career because of me. I took Klitschko’s belts off him then had my problems and the other guys picked them up. Charles Martin would never have had a world title for AJ to win off of him without me.
“I destroyed Klitschko, mentally, physically and spiritually and took every belt he had. Then they were all taken off of me and other people picked them up. I helped them all become world champions.”
