On June 1 at Madison Square Garden in New York, Anthony Joshua defends his WBA, IBF, IBO and WBO world heavyweight titles on against Andy Ruiz.
The contest will be Joshua's debut in the United States.
The 2012 Olympic gold medal winner wants to march forward to become a superstar on American soil.
Joshua believes that he's getting better with each passing fight.
But he doesn't view his rivals, Deontay Wilder and Tyson Fury, in the same light.
He feels Wilder and Fury are already at their peaking point - and neither will be growing as a fighter.
“The old-school generation had to read books to figure out certain information,” Joshua told Complex News.
“Now, if I typed into YouTube ‘how to become the best heavyweight boxer’, there’ll be so much information out there. So now, my improvement has to be coming thick and fast. The longer I’m in the game, the better I become; the more dedicated I am, the more passion I have to the sport to get better.
“The longer these other heavyweights leave it and they don’t fight me now, the tougher it’s going to be for them to beat me. I don’t think the other heavyweights are going to improve too much, because they’ve been doing professional now for 10, 11 years. They’re kind of at the stage now where you plateau.
“Unless they’ve got another gear, I don’t know. But I don’t think so.”
Fury is scheduled to fight on June 15th, when he makes his Las Vegas debut against Tom Schwarz at the MGM Grand.
Wilder makes a mandatory defense of his WBC heavyweight title on Saturday night, against Dominic Breazeale at the Barclays Center in Brooklyn, New York.
