A future match-up with Joshua would undoubtedly land both fighters the most lucrative payday of their career.
Okolie, a top-10 cruiserweight who represented Great Britain at the Rio 2016 Olympics, has sparred both men, therefore having a unique insight into each fighter.
Part of the same management company as Joshua, who he refers to as his “manager and friend”, the 26-year-old’s views are naturally skewed, but he speaks honestly about both men.
“They’re very different but both very good, so it’s quite hard to,” he tells Express Sport, before veering off into another point.
“They both possess very different qualities but very good qualities.
“Obviously I believe AJ would win, but it’s world-class heavyweight boxing so anything is possible.”
As far as all-British match-ups go, the event would doubtless rank among the biggest fights in history.
On the prospect, Okolie opined: “Overall, I think in terms of spectacles you go back and look at, it would definitely be up there.
“The whole world of boxing wonders who would beat AJ vs Wilder, AJ vs Fury.
“It puts them into legendary status – win, lose or draw.”
