Like all great boxers, Kostya Tszyu's son Nikita isn't shy when it comes to describing what he's aiming for at the world junior boxing championships in Ukraine this August.

"I just want to win it," he says.

"I only have one job. Win gold. I have a good chance."

The 15-year-old has already fought in six international bouts, losing two.

Having won the 54kg national title in January, Tszyu says he's especially looking forward to a rematch with a particular American opponent that apparently got the better of him.

"He was a very good fighter, very awkward, very fast," he said.

"I thought I won the fight."

"I want to get the rematch. Get what I deserve. I am just going to try and be faster, be stronger and be one step ahead."

A promising young soccer player, Tszyu decided to give away the sport to concentrate on boxing when he was 12-years-old.

He's since won three national boxing titles.

"Football was very good for me because it made me very quick on my feet," he said.

"But I don't really like team sports. I don't like depending on other people to help me out. I like having all the responsibilities on myself. I work hard by myself and I get all the results by myself."

He expresses a similar sentiment towards independence when it comes to his Boxing Hall of Fame inductee father, who only returns to Australia from training professionals in Russia a few times a year.

"It makes me tougher. It makes me stronger. Motivates me to show my dad that I am a good boxer even without you," he said.

Far be it from being sick of comparisons to his father and his brother Tim, who recently gave boxing away at the age of 18, Tszyu says he plays it to his advantage.

"I get used to it," he said.

"It motivates me to try and be better than him."

For the next week Tszyu will be training at the Australian Institute of Sport in Canberra as part of a junior boxing camp.

He says training at the AIS allows him to learn different moving techniques to those he practices at his uncle Igor Goloubev's Tszyu Boxing Academy gym in Sydney.

"I usually get taught more countering but here I'm getting taught to move to the side more," he said.

Despite enjoying what the AIS has on offer, Tszyu says he's more interested in turning professional than competing at the 2016 Olympics in Rio de Janeiro, Brazil.

"I reckon it will be too late for me as I want to get into pro as early as possible. It's better," he said.
