Tyson Fury has promised WBC heavyweight champion Deontay Wilder will meet "the best Tyson Fury" when the pair do battle for a second time in Las Vegas on February 22.
Since the first fight in December 2018, when 'The Gypsy King' had to settle for a controversial split decision draw, the 31-year-old has extended his unbeaten record to 30 fights.
While Fury had to haul himself off the canvas twice 14 months ago, he entered the bout not long after ending a two-and-a-half-year exodus from the sport in the wake of his stunning victory over Wladimir Klitschko.
"I believe I can outbox Deontay Wilder very, very comfortably but the fact of the matter is I believed I outboxed him last time and it is no good me believing it, the judges have to believe it.
"To guarantee a victory, I have got to get a knock-out. I don't want to leave anything unturned this time and I don't want another controversial decision. I want it to be defining either way."
If Fury was to defeat Wilder once and for all, it would mean the Manchester-born boxer would finally win the WBC belt, after holding the WBA, IBF, WBO, IBO and The Ring magazine belts after beating Klitschko in November 2015.
"I always like challenges," he said. "The WBC is one that has escaped me over the years.
"For whatever reason I have not got my hands on it yet and it would finish off my collection of all the belts out there. It would be nice to finish the collection off for sure."
Back in October, Fury told the PA news agency he would retire from the sport after three more bouts starting with his second clash with Wilder.
A potential third contest could be on the cards regardless of the result on February 22, but the British fighter is not interested in his legacy.
Instead, he pondered the prospect of being known as the best of his era if he can get the better of the 34-year-old.
Fury insisted: "When I am finished with boxing, I don't care about legacy, but the fact of the matter is I care about being active and I care about what is happening now.
"I think winning this fight would make me the best of my era. No more to prove.
"Everyone else has been defeated because it's only me and Deontay Wilder who are left unbeaten after 12 years as professionals. It is all on the line for this fight and it is a massive bust to win."
