“Look at his size and chin and his heart to keep getting up off the floor, he gets up. 

“He would be a stand-out performer in any era, for anybody.”

Even if Joshua regains his WBA, IBF, and WBO belts from Oleksandr Usyk next year, Warren believes the 31-year-old will be concerned.

“Look at the comparison between Tyson’s and AJ’s last performances. If Joshua has just watched that, it will have frightened the life out of him,” Warren added.

Fury’s American promoter Bob Arum, who promoted legend Muhammad Ali, said: “I’ve been in this business 57 years and I have never seen a heavyweight fight as magnificent as this.”

Fury could face compatriot Whyte if the 33-year-old defeats Otto Wallin on October 30.
