Tyson Fury has already delivered a polished and unblemished dossier during his 12-year career.

If you ask the 31-year-old Fury (30-0-1, 21 KOs), every heavyweight in history might as well be a dosser, because he unabashedly believes there isn’t a fighter past or present who could present him a challenge, let alone win a fight against him.

Months after defeating Deontay Wilder and capturing the WBC heavyweight title, Fury is still riding the high of a career-defining and confidence-boosting win.

The complete performance versus Wilder has also introduced a new layer of braggadocio for the affable British boxer.

“There isn't a heavyweight from any era in the last a thousand years that could've tackled me or beat me,” Fury told BT Sport. “Going right back to the beginning, not one of them would have beaten the Gypsy King. I'm too big, I'm too good and I've got too many styles for them. I'm an adapter and they couldn't even beat me anyway … Never mind Mike Tyson from the 80s, Muhammad Ali, Joe Louis, Lennox Lewis, George Foreman, Ken Norton, Rocky Marciano, Floyd Patterson, Gene Tunney, Jem Mace, John L. Sullivan.

“One, I’m too big. Two, I’m too good. And three, I’ve got too many styles for them. Four, I’m an adapter. And five, they couldn’t ever beat me anyway. So, there we go. I’m the greatest fighter that ever lived. never mind Heavyweight, the greatest fighter that has ever lived. How about that for [modesty]?”

Fury is convinced he’s already “The Greatest,” a title bestowed on Muhammad Ali.

The lineal champion Fury has scored wins over Wladimir Klitschko, and Dereck Chisora twice, but his hit list of big-name opponents falls short soon after.

If Fury were to successfully go through the current gauntlet of heavyweights, including another matchup with Wilder, and what seems like two matches with Anthony Joshua thereafter, he could pound his chest as the greatest fighter and heavyweight of his era.

As for the greatest boxer ever? That's a big boast to live up to, and it surely will be up for massive debate now, or even when his career is complete.
