Johann Duhaupas has promised to "embarrass" Anthony Joshua, should the heavyweight pair ever go one-on-one in the ring.
The 37-year-old evergreen Frenchman recently suffered a defeat in a bout against American Deontay Wilder, but that seemingly hasn't dented his confidence.
Meanwhile, Brit Joshua remains an unbeaten unified heavyweight champion following on from a points victory over New Zealand's Joseph Parker at Cardiff's Principality Stadium at the end of last month.
The triumph in the Welsh capital means that the 28-year-old Watford fighter now boasts the IBF, WBA, IBO, and WBO belts, sweeping the board, and only avoiding the title that Wilder himself holds.
Joshua and his management remain on the look-out for a next big pay-day, with various opponents mentioned.
Though, it has recently emerged that Joshua has been told that he must fulfill his obligated fight with Russia's Alexander Povetkin, which means his dream fight with Wilder will be put on hold until later on in the year.
However, while Joshua's achievements have been lauded over in recent weeks and months, his success doesn't sit well with Duhaupas, who believes that he could teach him a lesson in the ring.
Duhaupas, who has fought 41 times during a prolonged career at heavyweight level, feels Joshua has the self-confidence levels needed to be a success in the sport.
But, the former European heavyweight champion, who is currently ranked no.14 in the world by BoxRec, would relish coming up against 'AJ', who is nine-years his junior, in a showdown that would see the pair go toe-to-toe against one another.
And Duhaupas wants to "embarrass" the undisputed heavyweight, if they ever get the chance to meet one another for belts.
“Joshua is full of confidence right now, and he feels he is the best. In terms of absolute self-confidence, he is the best. But I would really like to face him because I know I can embarrass him enormously,” the Frenchman said exclusively to World Boxing News.
