Cuban heavyweight Luis Ortiz (29-1, 25 KOs) returned in style last Saturday night at the Staples Center in Los Angeles, California.

He knocked out Razvan Cojanu in two rounds, with a single big shot.

It was Ortiz's first bout since suffering the first defeat of his career back in March, when he was knocked out in ten rounds by current WBC heavyweight champion Deontay Wilder.

Ortiz has been calling for a rematch with Wilder - but he also wants a showdown with WBA, WBO, IBF, IBO heavyweight champion Anthony Joshua (21-0, 20 KOs).

Joshua is back in September 22nd, when he faces WBA mandatory challenger Alexander Povetkin at Wembley in London.

At one point in 2016, Ortiz signed a multi-fight deal with promoter Eddie Hearn in order to secure a fight with Joshua - but it never happened.

"I haven’t thought about Joshua since he avoided me a while back, but it’s a fight where you would see me enjoy beating the piss out of him for several rounds. I see myself breaking down Joshua to the body and ripping his head off with right hooks and straight left hands over the course of eight rounds," Ortiz told Premier Boxing Champions.

"But at least Wilder put his money where his mouth is, stepped up and fought me. I’ve got zero respect for Joshua, who, at this point, is a complete punk hiding behind his puppeteer promoter [Eddie Hearn]."

Ortiz is getting close to 40-years-old - but he says his age is not making big fights any easier to secure.

"I could be 50 and still beat these guys. They ain’t [better than me]. If my age is such a big deal, why isn’t Joshua calling me out? Why isn’t Wilder giving me an immediate rematch? Why are all of these punks running from me? Obviously, they don’t want to fight and they’re all scared of me," Ortiz said.
