After defeating Deontay Wilder to regain his WBC title, Tyson Fury declared himself the "greatest heavyweight of my era".
Following two knockdowns in a dramatic third fight, the 33-year-old defeated Wilder in the 11th round.
I am undoubtedly the greatest heavyweight champion of my time. Number one. Playing with fire for too long will burn you."
Twenty months after a disputed draw, the unbeaten Fury stopped their second battle in the seventh round.
Fury fled the arena after defeating Wilder for the second time on Saturday, saying the American didn't want to fight.
"I went over and said well done and he said he didn't want to show any sportsmanship or respect," he added. That astonished me. He's stupid.
Wilder, who was hospitalized after the fight, said he "wasn't good enough" that night.
I'm not sure what happened," he said. "I knew he did certain things in training and didn't weigh 277lbs to be a ballet dancer.
At their career-heaviest, Fury had 39lbs on Wilder, but the Morecambe fighter thought Wilder was too hefty at 17st.
