Heavyweight contender Dominic Breazeale believes WBC world champion Deontay Wilder made a very big mistake.

He says Wilder should have accepted an offer to face IBF, IBO, WBA, WBO champion Anthony Joshua in a unification last year.

Wilder took a pass on what he felt was a very low offer, and instead faced off with Tyson Fury in December of the same year.

Wilder will make a mandatory defense against Breazeale on Saturday night at the Barclays Center in Brooklyn, New York.

Breazeale doesn't expect the fight to ever happen, because he expects to knock off Wilder this weekend.

“Wilder’s had a great deal on the table, whenever he was working with Joshua and I think he should have taken it because come May 18, I’m going to ruin everything,” Breazeale said.

“I’m going to put my name in that hat with Joshua and I definitely want my revenge against Joshua so we’re going to make some things up in the near future. My way to do that is to get my WBC title and that’s what I plan on doing.”

Should he capture the WBC title from Wilder, Breazeale wants to face whoever holds the other remaining belts - and he wants to fight the other top names in the division.

“Of course you always want to see the title holders fight each other. But right now I think those five names mentioned, myself, Andy Ruiz, Tyson Fury, Wilder and Joshua, we are the top of the division and the fans are getting exposed to what they want to see," Breazeale said.

“They’re getting exposed to a heavyweight fight. When I fight Wilder May 18 it’s not going to be boring. It’s going to be action packed. It’s going to be big punch after big punch.

“And the thing with Joshua and Andy Ruiz, I’m excited to be part of the division. I’m excited to be where I am now standing. I’m also super excited to be the spoiler.”
