London - Anthony Joshua has offered to be Tyson Fury's sparring partner if it helps his fellow British fighter beat WBC heavyweight champion Deontay Wilder.
Joshua has been left frustrated in his attempts to lure America's Wilder into the ring as he bids to unify the division following his victory over Andy Ruiz Jr last weekend.
The 30-year-old, who regained the WBA, IBF and WBO belts, feels he has a better chance of landing a blockbuster unification showdown with Fury than with Wilder.
Fury faces a re-match with the American on February 22, having drawn their first encounter, and Joshua told Sky Sports News: "I think honestly he might beat Wilder next time.
"I think Fury would fight me quicker than Wilder would, so, if that's the case, I want him to win. Imagine that fight on British soil.
"If Tyson needs me, I'll go out and spar with him to get him ready for Wilder."
Joshua remains desperate for a showdown with Wilder that would see both men attempt to become the first undisputed heavyweight champion since Lennox Lewis.
"It still puzzles me as to why it's so difficult to pin this man down," Joshua said. "This is the man I need to pin down to get the last ring and conquer this division."
"You've got the two lords of the rings here," he added. "The last one to unify, undisputed, the division. I've got four (including the IBO belt), he's got one. I just need one more."
Bulgarian Kubrat Pulev is the IBF's next mandatory challenger for Joshua, while the WBO has ordered the Londoner to fight Ukrainian Oleksandr Usyk.
And speaking about a potential third meeting with Ruiz Jr, the Mexican-American who stunned the boxing world by beating Joshua in June, the British boxer said: "One trillion per cent.
"I always said I'd fight him in Tijuana, with his uncle as referee. Me and Andy will soon see each other in the ring again."
