Jeff Horn says he will use the crowd's boos as motivation when he meets Terence Crawford on June 9th, live on BoxNation.
After scoring a huge upset win over Manny Pacquiao last summer, Horn gatecrashed the Welterweight party and took the Filipino's WBO World Title.
Last November, Horn stopped Gary Corcoran in Brisbane, and next month he makes the second defence of his belt in Las Vegas.
There has been some trash talk between the two camps, with the two trainers exchanging words, but Horn believes the American's team are just trying to get inside his head.
"They’re trying to make me feel nervous and to doubt myself, but I haven’t done that for a second," 'The Hornet' told Fox Sports.
"I’m not scared of this guy. You have to be confident in boxing, if you go in there thinking you’re going to lose then that’s exactly what will happen."
Crawford is moving up from 140lbs, where he cleaned up to win all four major championship belts, and can become a three-weight World Champion if he defeats Horn.
"He has a devastating left hand, he can hurt you in the body or in the head," admitted the Australian. "He’s able to switch-hit. But that’s all right, I have a few plans of my own.
"It won’t be like Brisbane, that’s for sure. There will be plenty of boos, but you can use that to your advantage as a fighter, too.
"I’ve worked harder for this fight than I ever have. I’ll be pushing hard, pressuring him throughout the fight. I’ll be thinking about my family, about my wife and daughter, going to the places that lift me when I need to dig deep," added the 30-year-old.
