As Joshua prepares to face ex-top division king Wladimir Klitschko on April 29 in London, Wilder believes the Olympic gold medallist lacks the experience to trouble him right now.
“I definitely feel like I’m on a whole other level than Joshua,” Wilder told FightHype.com.
“I’ve been in this game for a while now. I’m very experienced. I think I’ve seen every style to see, you know, the major styles that I need to see.
“I think I’ve seen it, I’ve learned it, and that’s what allows me to adjust in the ring and do my thing.
“I definitely feel and know that I’m in another league of my own when you compare the two of us.”
Asked about the rest of division, the American did admit a clash with Joshua would be the most appealing to the fans.
“I mean, if you look at Joshua, Klitschko, and Parker, Parker has the WBO belt, and you take those three and put me up on a chart and say which one would be the most exciting fight, a lot of people would think the Joshua fight would be the most exciting fight out of the three and I think I agree,” he added.
A huge Wilder v Joshua unification is being lined up for Showtime PPV, potentially in late 2017 or the summer of 2018, provided the latter comes through his Klitschko test impressively at Wembley Stadium this month.
Joshua has so far bulldozed his way through his opposition, and with Klitschko in his twilight years, a knockout win could be on the cards to make the rest of his rivals sit up and take notice.
