Unbeaten puncher Filip Hrgovic would love to get in the ring with former two-time heavyweight champion Anthony Joshua.
Both men are guided by Eddie Hearn's Matchroom Boxing.
Joshua is planned to return in the month of August, before a potential fight with former WBC champion Deontay Wilder on a December date in Saudi Arabia.
The frontrunner to face Joshua in August is Dillian Whyte, but Hearn indicates that Whyte is not happy with the money, and they appear to be far apart on what they respectively believe the rematch is worth.
Joshua last saw action back in April, with a twelve round unanimous decision over Jermaine Franklin. It was Joshua's first fight with new head trainer Derrick James of the United States.
The victory snapped a two-fight losing streak, after dropping back to back fights to unified champion Oleksandr Usyk.
Hrgovic, with 12 knockouts in his 15 wins, is the IBF's mandatory challenger.
If Joshua is unable to reach an agreement with Whyte, then Hrgovic is ready and willing to step in there.
And, Hrgovic believes that his power and boxing ability will propel him to victory.
“I’ll destroy him. I think I’ll destroy him. If he comes in this shape [like he did against Franklin] I’ll destroy him. I expected more [against Franklin]. I thought he was going to knock him out, but he was too cautious and didn’t let his hands go," Hrgovic told Boxing News.
“It was a decent performance but nothing spectacular. He needs more fights to get back into real shape. People expect to see more from the former two-time champ.
“He was a little bit slow and sleepy, not aggressive. If he wants to become champion again then I’m in his way. I’m IBF mandatory and he should fight me next.”
