Tim Tszyu is targeting October or November and a dream destination of Las Vegas for his title shot at undisputed super welterweight boxing champion Jermell Charlo.
The WBO recently ordered promoters to commence negotiations for a mandatory bout between No.1 contender Tszyu and American Charlo, with their teams reportedly agreeing terms.
But there is a problem with the camp of Russia's leading IBF contender Bakhram Murtazaliev adamant their fighter's mandatory shot should be first, insisting they have a contract for a fight with Charlo.
"If they need that insurance then I'll fight him (Murtazaliev) next (after Charlo), that's not a big deal," Tszyu said at the announcement of a July 20 fight in Sydney between his younger brother Nikita and Ben Horn.
"The boys are working on October, November roughly around that time period. I'll be ready to go then.
"There's a lot of politics including the mandatories, but I'm sure the boys will get it done. The fight is gaining interest, a bit of momentum, it looks like it will be happening."
Murtazaliev fought on the same card in America when Tszyu had his last fight and the Australian believes he is the more attractive opponent.
"Bakhram was a couple of fights after me when they were taking out the seats," Tszyu said.
"If you see it from a seller's point of view, me and Charlo makes sense."
Tszyu, who is recovering well from hand surgery two months ago, dismissed the suggestion from some quarters he wasn't ready to fight an undisputed champion.
"That's what makes you great when people doubt you and say this and that and you prove everyone completely wrong," Tszyu said.
Tszyu stopped former WBO welterweight champion Jeff Horn in Townsville back in August 2020 and their younger brothers will headline next month's card at the Hordern Pavilion.
"I want to restore family honour of course but I think all the pressure is on him, " Ben Horn told AAP.
"I definitely don't think I'll be stopped in the first two, three, four at all, I do believe it will go the distance."
Nikita has already impressed critics with his power, scoring second and first-round stoppages in his first two professional bouts.
"The best thing to happen for him is to go a couple more (rounds), but I don't think this is the fight," Tim Tszyu said.
Nikita said his father Kostya Tszyu, the former unified junior welterweight world champion, had told him he did a good job in his last fight despite a few mistakes.
"I'll always cop a few shots but give a few back. There's something satisfying in copping a shot and giving one back that's twice as hard," Nikita told AAP.
A stacked undercard features a bout between IBF No.9-rated junior featherweight Sam Goodman and former WBO world title challenger Juan Miguel Elorde, plus a number of other crowd pleasing fighters including Ty Telford and Darragh Foley.
