Anthony Joshua: If Tyson Fury needs me, I'll go out and spar with him to get him ready for Deontay Wilder

Anthony Joshua has offered his services as Tyson Fury's sparring partner if it hels his fellow Brit dethrone Deontay Wilder.

With Joshua, Fury and Wilder all signed up with different promoters, getting them in the ring has proved a huge source of frustration for boxing fans over the years.

Joshua, in particular, has been stymied in his attempts to lure WBC heavyweight champion Wilder into the ring as he bids to unify the division.

Joshua holds the WBA, IBF, WBO, and IBO belts following his victory over Andy Ruiz Jr last weekend at "Clash on the Dunes" in Saudi Arabia. The Briton, 30, 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 in Los Angeles last December, 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."

Nevertheless Joshua, 30, remains desperate for a mega-fight with Wilder which 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 added.

"This is the man I need to pin down to get the last ring and conquer this division.

"When he's ready, as I am, I would love to be here talking about Deontay Wilder and the keys to victory.

"It's not about me, it's about the sport and the legacy. If he wants to create his legacy and he wants to be a future hall of famer, he needs to come and see us.

"You've got the two lords of the rings here. The last one to unify, undisputed, the division. I've got four, he's got one. I just need one more."

In the meantime Bulgarian Kubrat Pulev is the IBF's next mandatory challenger for Joshua, while the WBO has ordered the Londoner to fight Ukrainian Oleksandr Usyk.

"Pulev is a very tough athlete," said Joshua. "He knows what he's doing and anyone fighting for the championship is a dangerous fighter. My mindset? Seek and destroy.

"Usyk is a great cruiserweight has moved up to be in with the big boys. He will be in my sights for around March or April, and he's a very credible opponent.

"I want fighters like him on my record. I've been studying him already."

There is also the potential for a third installment against Ruiz, something both fighters stressed before and after Joshua's unanimous victory on December 7 in Diriyah.

The Mexican-American caused one of the biggest upsets in heavyweight boxing history when he knocked the previously undefeated Joshua down four times on his way to a seventh-round stoppage in New York on June 1.

"One trillion per cent," Joshua said. "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."
