IBO/WBA/WBO heavyweight champion Tyson Fury has become the target of undefeated prospect Dominic Breazeale, who is not impressed with the unified champion's boasts of what he could do.

Breazeale says IBF heavyweight champion Anthony Joshua (16-0, 16KOs) is more dangerous than Fury. Breazeale and Joshua collide on June 25th at the O2 Arena. It's the first defense by Joshua since destroying Charles Martin in two rounds earlier this month, also at the O2.

Fury (25-0, 18KOs) has a rematch in place with Wladimir Klitschko on July 9th in Manchester. He captured the titles from Klitschko last November in Germany.

When Breazeale was announced as Joshua's opponent, Fury took to social media and trashed his credentials as a challenger.

"I'm really sick of him getting on social media and saying all this nonsense and what not," Breazeale told Sky Sports. "In the fight game you can talk all you want outside the ring. As soon as you get in the ring, you've got to fight. There is no more talking going on."

"I know that fight is coming down the pipeline pretty soon. But one fight at a time, I want to take care of Anthony Joshua first and go from there. At this point he kind of reminds me of Shannon Briggs. Shannon Briggs just runs his mouth and he tries to buy himself a fight. I've got no respect for Tyson Fury or Shannon Briggs. I only can respect a guy that gets in the ring and handles his business."

"I think it's going to be a lot easier task beating a guy like Tyson Fury than it's going to be, going in the ring with a guy like Anthony Joshua. Anthony Joshua is a humble guy, he understands what he does, very confident dude."

Breazeale also picks Klitschko to avenge his loss with a big knockout.

"It was a tough fight against Klitschko, but it wasn't Klitschko's best," said Breazeale. "He had a bad night, he had an off night, he's a human being, and at the same time, they've got a rematch coming up, but I think Klitschko is going to prove to the world who the real heavyweight champion is. Do I think Klitschko stops Fury? Oh yes definitely, he knocks him out."
