Tszyu knocked Morgan out one minute and 54 seconds into the first round to move one step closer to a world title shot.

The 26-year-old moved to 17-0 when he dropped Kiwi rival Bowyn Morgan (21-2) twice in the opening round before it was waived off in front of 11,820 at Western Sydney Stadium on Wednesday night.

Now the face of Australian boxing wants everyone to know what's next.

"You guys know what's next, that's the world title here in Sydney in Australia," Tszyu said.

"Let's do it 10 times the size of this. Australia deserves this. I'm Aussie born, and for my Russian fans also, utmost respect to you guys. This is for everyone.

"It was hours and hours, countless hours in the gym perfecting my craft. This doesn't happen without the hard training I go through. I was just getting started. Bowyn Morgan is a tough competitor, I just never gave him an opportunity.

"My respect to Bowyn, I respect all my opponents. To step into this ring takes balls, it takes guts."

The World Boxing Organisation announced this week Tszyu is next in line to fight for the world junior middleweight title.

If current champion Patrick Teixeira and No. 1 ranked challenger Brian Castano cannot secure a bout by January 6 - which seems an unlikely task given coronavirus restrictions - then the champion could be stripped, opening the door for Tszyu to fight Castano for the WBO strap next.

The winner of that would take on Teixeira, given the champion would only lose his crown due to restrictions beyond his control.

The prospect of this fight being effectively upgraded to a world title eliminator for the hometown favourite left Tszyu with the task of staring down an opponent with an even bigger opportunity hovering just over his shoulder.

The last time a face of Australian boxing was faced with that situation, Michael Zerafa said sayonara to Jeff Horn's dream of a middleweight world title fight with Ryota Murata in Tokyo.

Among the crowd watching Tszyu climb the next rung on the ladder were the NRL's Dally M medal winner Jack Wighton, AFL superstar Dustin Martin, NRL trio Latrell Mitchell, Damien Cook and Cody Walker, UFC featherweight champion Alex Volkanovski, and boxer Jack Brubaker - once Tszyu's opponent.

But perhaps the most intriguing spectator was Zerafa himself, who was once part of Tszyu's four-fight plan before knocking back an offer after claiming he was low-balled.

"Now the list [of potential opponents] goes on. I only want one thing, that's the world title strap here in Australia," Tszyu said.

Next month marks 25 years since Kostya Tszyu stopped Hugo Pineda in a super lightweight title fight at the old Parramatta Stadium - the site of the multi-million dollar his son fought in tonight.

Now it may well host the new Tszyu's first shot at a world title.
