Hughie Fury has predicted a crushing defeat for Anthony Joshua and would be willing to face Wladimir Klitschko as he attempts to reclaim the world titles for his family.
IBF champion Joshua has become embroiled in a Twitter row with Fury's cousin Tyson as he prepares to face Klitschko at Wembley Stadium on April 29, live on Sky Sports Box Office.
Hughie wants Joshua to claim victory, despite the war of words between 'AJ' and Tyson, the former unified champion, but fears the 27-year-old's lack of experience will be brutally exposed by Klitschko.
"Yes, definitely be tuning in for that one, it's going to be an exciting fight," said Fury, who is preparing for his own world title fight against WBO champion Joseph Parker.
"I do think it's a tiny bit soon for Joshua, but I do wish him all the best and I hope he wins. I would go with Klitschko with the experience. I just think it's a tiny bit too soon for Joshua. Definitely a knockout.
"He wasn't an 11 year champion for nothing. Like I say, you cannot rush into big fights like him, thinking 'yeah I'm just going to knock him over like every other man'.
"He's not going to stand there to be hit. He's not had the experience to go with someone like him."
Asked if he would consider a future fight with Klitschko, Fury said: "Definitely, it would be another exciting fight.
"It doesn't really matter. It would be nice if Joshua pulls it off, but we'll see."
Fury can regain one of the world titles which were vacated by Tyson last year when he challenges Parker in New Zealand on May 6, and hopes to then battle the other remaining champions.
The 22-year-old said: "I'm not looking past anyone at the moment. I'm looking forward to Parker, and after one belt, I'm coming for them all.
"I want to unify the heavyweight division - and that is what I will do."
