Michael Katsidis insists Amir Khan is motivated only by money and will continue to avoid a showdown.
Katsidis meets Scotland's Ricky Burns for the interim WBO lightweight crown seeking the victory that will propel him back into world title reckoning.
Among the brawling Australian's preferred opponents is Khan, Britain's double world light-welterweight champion who he insists would be unable to live with his power.
"Amir's had two opportunities to fight me but for him it's all about the money," said Katsidis.
"He wants to keep it all for himself and leave nothing for the opponent.
"He's shied away from me in the past and I believe he's just waiting for me to get old. He might be waiting a while.
"I don't think he'll step up to the fight. We held talks and they tried to put the money thing on us.
"Every day I'd beat him. I'd be more confident about beating Amir than about beating Ricky Burns.
"I've not had a fight where I've not hit someone at some point.
"The moment I hit Khan I will knock him out. I saw him against Marcos Maidana from ringside and he was gone.
"In 12 rounds I will hit him on the chin and he will go down."
Katsidis, dubbed the 'Brit Basher' after stopping Graham Earl and Kevin Mitchell in brutal fashion on previous visits to London, has more targets from the United Kingdom in his sights.
The most famous of those is Ricky Hatton, who Katsidis is hoping to lure out of retirement with the help of mutual friend Graham Earl.
"I've been hanging out with Graham Earl and we were talking about a fight with Ricky Hatton. This can happen," he said.
"He's walking around fat as a blimp right now but he's an absolute legend of the sport and if anyone can pull it out it's him.
"The only discussions I've had are with Graham and Graham is good friends with him. Graham and Ricky are talking.
"He's been in the gym and has been getting hungry again while he's been training people."
Katsidis represents a formidable challenge for Burns, who will be making his debut at lightweight having vacated his WBO super-featherweight title following three successful defences.
"Ricky Burns is in with the big boys now, but I'd say he realises that," said Katsidis. "I'm established at lightweight so he can take on anyone from here, win or lose.
"It will be a tough fight. It's a brave move by him but it's risky for me too because he's an accomplished fighter."
Burns, who continues to hold a Saturday job at a sports shop, is seeking his 33rd victory in 35 fights.
The 28-year-old Scot is braced for the toughest encounter of his career believing that an adaptable gameplan represents his best chance of success.
"Michael is a great fighter and he's proved that at the top level," said Burns.
"Even though he's lost two of his last three, he was only beaten by Juan Manuel Marquez and Robert Guerrero, who are at the top of their game.
"In my last few fights I've been getting more aggressive but I can go back to boxing when I want to.
"I don't know what way I'm going to fight. I've been working on a lot of different things in the gym, but in this fight I'll be operating on instinct.
"If the boxing's working I'll stick to that, but if the two of us go toe to toe, then that's the way it will be.
"I've seen Michael fight in the past but since the fight was announced I haven't watched any footage of him.
"I'm a believer that whatever happens on the night will happen. I want to concentrate on myself."
