Anthony Mundine and Shane Mosley say their October 23 bout in Sydney is all about working towards a showdown with American boxing superstar Floyd Mayweather.
Known for his "wild talking" when promoting fights, Mundine made it clear at Wednesday's media conference with 42-year-old Mosley that the lead up to their clash would be different.
Mundine denied the pair were "really good friends", despite meeting in the US last year and Mosley having made several trips to Australia in the past.
Instead, he said the chummy atmosphere at the media conference was due to mutual respect, and would change once the fighters entered the ring.
The 38-year-old Mundine, with a professional record of 44 wins from 49 fights, said undefeated world champion Mayweather was a realistic opponent if he could get past Mosley.
"I've told you guys a year ago or so I wanted to fight the best fighters out there and since my last fight I've spent 10 months always staying in shape," he said.
"I don't want to fight contenders. I want to fight the best, the very best, to prove that I'm up there.
"It took a while but I've got this fight to showcase the skills I have and everything that comes with it. And that can snowball to bigger ones but I'm not looking past this.
"I've got to show (Mosley) the utmost respect he deserves."
Mundine stood by a previous suggestion that he could retire if he lost to Mosley.
"You'd definitely have to look at it," he said.
"In my mindset I'm not even thinking about (retiring). It's only going to go one way and that's victory."
Mosley has never been stopped in 56 professional fights and despite losing four of five bouts since 2009, the future Hall of Famer's record still suggests he is one of the greatest pound for pound fighters of all time.
However for this fight he will need to go up to 154 pounds from his usual fighting weight of 147, with Mundine coming down slightly from the 157 he fought at against Daniel Geale in January.
Mosley has been accused of being "punch drunk" by critics, but said he was fully fit and sharper than when he fought Mayweather and went down swinging back in 2010.
Mosley is in Sydney unusually early, touching down a week ago to try and get the most out of his preparation.
The Californian said he was after a rematch with Mayweather.
"I'm injury-free, that's what's important and people are going to see the old Shane," he said.
"The old Sugar Shane back in the day top of fighting. And the one you saw when I fought Pacquiao and Mayweather... I'm ready.
"I definitely (want a rematch). Not just with Floyd but Marquez and Manny Pacquiao. I'm looking forward to those chances."
