IBF, IBO, WBA, WBO heavyweight champion Anthony Joshua will be keeping a close eye on Saturday night, when Deontay Wilder defends his WBC world title against Dominic Breazeale.

Joshua faced Breazeale back in June 2016, and stopped him in seven rounds

Willder will collided with Breazeale at the Barclays Center in Brooklyn, New York. The bout will be carried by Showtime and Sky Sports.

Joshua, who is currently training in Miami, makes his United States debut on June 1 when he faces Andy Ruiz at Madison Square Garden in New York City.

"Yeah, yeah 100 percent," Joshua told Sky Sports, when asked about watching Wilder.

"Styles make fights, I think Wilder will fare well against Breazeale. I think Wilder is too quick, he's a very, very fast heavyweight, but Breazeale is tough, took me seven rounds. I hope Wilder does it in nine, so I can be like 'hey I done it earlier'. You know how it is, comparisons and stuff, but yeah it will be interesting to see.

"You look at the small things, I look at the small details - when he's getting tired, how many right hands he throws in a round. I look at something different, rather than comparisons to the rounds."

Joshua has a lot of respect for Breazeale and believes the California fighter is very durable and capable of creating problems for Wilder.

"When I looked at his interview after and I saw his face, I said wow you definitely took a beating, and he stayed in there," said Joshua.

"He got hurt in the second round, stumbled, stayed on his feet. Come game, it's a world championship fight, that's what I'm saying. Breazeale at the time, he may not have been Wladimir Klitschko, but he came and put up a fight."
