Despite becoming World Champion last summer, Jeff Horn still feels he has a lot to prove.
Horn caused one of the upsets of 2017 when out-pointing Manny Pacquiao in a brutal brawl in Brisbane, but some observers - ESPN pundit Teddy Atlas in particular - claimed the decision was a robbery.
On Saturday night he faces his toughest test in Terence Crawford. "I am treating it similar to the Pacquiao fight. I've got heaps to prove for this fight," he told the BoxNation Podcast.
"I feel like I didn't gain the respect that I probably deserved for that Pacquiao win. A lot of people don't think I actually won the fight thanks to the commentators.
"I don't let that type of stuff bother me. I'm not going to worry about all the naysayers," added 'The Hornet'.
Crawford has stopped seven of his last nine foes, and aims to become a three-weight World Champion with a win in Las Vegas.
While Horn admits the American is one of boxing's very best, he feels his size difference over the former Lightweight will be a factor in the second half of the bout.
"Look, I've just got to out-box him," he said in response to a question on tactics. "I know he's a supremely superb boxer and he can fight all different styles. But I think I've got a style that can upset anyone out there.
"I know my size won't be massively different to Terence, but it's definitely going to be an advantage in the later rounds, if it makes it that far. If either of us catches each other flush, I'm sure it'll be lights out."
In the unpaid ranks, Horn reached the quarter-finals at the 2012 London Olympics as a Light-Welterweight and travelled all around the world for tournaments. So the Aussie isn't worried about fighting in the States.
"It's been years since I've been this far overseas for a big fight. I'm really looking forward to showing my skills and showing my worth over there," he added.
