Undefeated Aussie boxer Tim Tszyu has hit back at taunts from Michael Zerafa, insisting his compatriot's fight against Anthony Mundine was disgusting and "disrespectful".
The 28-year-old Zerafa called out Tszyu after destroying 45-year-old Mundine in just two minutes when the pair fought in Bendigo earlier this month.

Zerafa demanded Tszyu "stop running" and step into the ring for a fight he claimed all Australian boxing fans wanted to see.
The boxer came under fire for taking on the fight against Mundine, who many thought should have walked away from boxing years ago.
Tszyu admits he couldn't even bring himself to watch the fight and questioned what Zerafa hoped to get out of it - apart from money.
“I couldn’t even watch it,” Tszyu told Fox Sports.
“I thought it was ethically not acceptable to watch, because there’s only one thing that’s going to happen."
Tszyu said Zerafa's two-minute non-event with Mundine should never have happened and insists he won't be used as a pawn for his rival to try and make a name - and money - for himself.
"I find the whole thing about him is he's trying to do a circus. He's trying to gain media attention," Tszyu told AAP ahead of his super welterweight battle next week with Irishman Dennis Hogan.
"If it wasn't for me, who's he going to fight?
"He sees himself as this A-class fighter and a pay-per-view fighter and in reality he's not.
"He's trying to use his mouth to get the fight."
Undefeated Aussie not interested in Zerafa
Tszyu said fighting 45-year-old Mundine was sad and disrespectful (even if he did inflate the veteran's age by a couple of years) and described Zerafa as a "last option".
"If there's nothing else on the table, then we'll pursue that," said the undefeated Sydneysider.
"You don't get an opportunity by beating a 47-year-old grandfather. Let's just say that.
"I've got top-10 options that I'm going for. The world title opportunities, the Liam Smiths, the (Magomed) Kurbanovs, the Danny Garcias, they're the boys I want.
"They're the big boys in the division that I want to play with.
"We got offered the Mundine fight and I said straight away it's not happening.
"It's disrespectful for Mundine. He's a grandfather, he's 47 years old. Who does that? There's a time when just enough's enough."
The 26-year-old Tszyu is focused on his pursuit of a world title but has a job to do against Hogan first when the pair meet in Newcastle next week.
"I'm improving as a fighter, I get better each time and I've been proving that to everyone.
"I'm targeting the big boys in the division. I'm going to get the opportunity to fight one of those guys soon, so I've got to be a hundred per cent ready."
Tszyu's ultimate goal is to fight either Argentina's WBO belt holder Brian Castano or potentially American Jermell Charlo, who boasts the WBA, WBC and IBF straps, in a unified mega-fight for all four titles.
