Tim Tszyu says he has "no interest" in fighting Australian boxing bad boy Michael Zerafa for now, and insists he will soon be the undisputed world super-welterweight champion.
Tszyu has also responded to upcoming American opponent Michael Harrison's claim that he is "stupid" to fight him for the WBO interim super welterweight title on March 12 in Sydney.
Tszyu already had a definite shot at the unified title against undisputed world champion Jermell Charlo lined up and just had to wait for Charlo's hand injury to heal.
The 28-year-old has put it all on the line to fight Harrison.
Zerafa has his own upcoming IBF world title fight against Brazil's Esquiva Falcao and said recently a showdown with Tszyu "has to happen".
Tszyu, in Brisbane to promote his Harrison fight, moved to put Zerafa in his place.
"He is a loudmouth. That is all he is," Tszyu said.
"With Zerafa there is only one thing. If he has got something presentable, like a world title, then so be it. That would be probably the easiest fight to win a world title, if he has got one.
"Besides that let him go and fight in shows with two hundred people. I am alright with that."
As for whether he would beat Zerafa, Tszyu was dismissive.
"Stuff him. Don't worry about him. I have no interest in him," Tszyu fired.
Tszyu had no qualms about the risk he was taking by fighting Harrison.
"The way I feel is just line them all up…all the fighters in the top five…line them up one by one and each one of them is going down. The whole world is going to know soon."
Harrison is the only boxer to beat Charlo, but Tszyu is not daunted by that.
"I know I will be unified (champion). I do a lot of damage. I am not speaking out of arrogance.
"The biggest thing I have learned is that under chaos and real stressful times in the ring, I remain calm.
"I feel most at peace when I am in that ring in the zone, when I am hammering my opponents and they have got blood coming out.
"It gives me a purpose and a belief that this is what I want to do, and this is what I am supposed to do."
Harrison's taunts didn't faze the Australian.
"In America that is how it is. Everyone is so good at talking there.
"Everyone is made for the radio. I don't talk as much, nor can I come up with his comebacks."
Tzsyu then pointed at his fists.
"These bad boys will do all the talking in the ring," he said.
"It has been a year since I last fought. The temptation to get into that ring is just unbelievable.
"The calibre of my opponent just excites me even more. The brashness and mouth going non-stop is all just part of the whole spectacle."
