Tyson Fury would "love" to have Anthony Joshua as a sparring partner in preparation for his WBC heavyweight title rematch against Deontay Wilder.
Two-time IBF, WBA and WBO champion Joshua made the surprise offer to his fellow Briton while assessing the landscape in his division during an interview with Sky Sports News.
Fury climbed off the canvas twice as he boxed to a thrilling draw against Wilder 12 months ago and Joshua believes he can prevail in the rematch.
The preparation is something Joshua suggested he would like to play an active role in, to set up a blockbuster showdown for all the major heavyweight belts.
"I think Tyson Fury would fight me quicker than Wilder does, so, if that's the case, I want Fury to win because I just want to fight [for the unified title]," Joshua said.
"Fury, if you need me for sparring. We're going to fight one day. I sparred Tyson Fury when we were kids anyway.
"I'd go out to America and spar Tyson Fury to get him ready for this Wilder fight. I would like that fight because I think Fury would fight me faster than Wilder would."
Fury, who announced the appointment of Javan 'Sugar' Hill as his new head trainer over the weekend, was quick to offer an affirmative response via his Instagram account.
"I just saw a video of Joshua on Sky Sports saying he'd love to come visit me in camp and that I'd fight him quicker than Wilder - that's for sure," the undefeated 31-year-old Fury said.
"When I beat Wilder, I will fight you AJ no problem and I'd love to have you in camp.
"I'd really love to have you in camp for this fight and give Wilder a proper beating.
"I hope you mean it because I'd love to have you in training camp. Thanks very much and well done in your last fight, congratulations."
Joshua comprehensively outboxed Andy Ruiz Jr earlier this month to avenge his sole career loss, and his initial 2020 schedule is set to be concerned with respective IBF and WBO mandatory challengers Kubrat Pulev and Oleksandr Usyk.
Nevertheless, Joshua expressed frustration over the fact a showdown with long-reigning WBC king Wilder has never been nailed down.
"It still puzzles me as to why it's so difficult to pin this man down," Joshua said.
"As I said, I fought Charles Martin to become [IBF] champion, Wladimir Klitschko for the WBA championship, Joseph Parker for the WBO championship, Andy Ruiz to become unified heavyweight champion.
"This is the man that I need to get the last ring so I can conquer this division as I've set out to do from day one.
"It's not even about me now; it's gone past that. This is about the sport and our legacy. If he wants to make his legacy and become a future hall of famer, he should come and see us."
