'Still a boy': Jeff Horn insults Tim Tszyu after boxer's win

Jeff Horn has lit the fuse for a fiery showdown with Tim Tszyu after issuing a derisory response to the young Aussie’s latest victory.

Super welterweight boxer Tszyu has added more belts and learnt some lessons after successfully passing his toughest professional test to date.

The 24-year-old Sydneysider was made to work by Victorian Dwight Ritchie on Wednesday evening in his home town, but earned a unanimous ten round points decision.

He won two regional super welterweight titles and should be knocking on the door of the IBF top five after improving his record to 14-0, with 10 KOs.

The young Aussie's latest win has fuelled more talk of a momentous showdown against former Aussie champion Horn, who offered his thoughts on Tszyu after the fight.

"Tim Tszyu is still a boy with a man's name," Horn taunted.

"He is still holding onto that Tszyu name.

"He has to build himself up a little bit more.

"Sure he is one of the best in Australia in that weight division, he is making inroads, he is doing great things for the sport but is he ready yet for that massive fight? I don't know.

"I would like to see him against some world class opposition."

The young Tszyu - son of legendary Aussie boxer Kostya - was equally as dismissive of Horn, insisting he needs to win his own upcoming fight against Michael Zerafa before they can entertain the thought of a blockbuster bout.

"I just proved I am the best in Australia, I have cleaned up my division, time to think about overseas, there are only a few fights in Australia left for me," he said.

"He (Horn) is here, once he finishes his task then we can talk."

Tszyu went into the fight in Sydney rated 12th by the IBF, three places below Ritchie.

Tszyu’s reputation grows after latest triumph

He entered the ring to the accompaniment of the Queen classic Another One Bites the Dust, a song released 14 years before he was born.

Tszyu did indeed add another victim to his record, but it was no cakewalk, as Ritchie made him work for a win the judges gave to him by margins of four, five and six points.

While Tszyu landed the more powerful blows, Ritchie kept him honest, firing off plenty of punches of his own in a willing contest.

"He kept me on my toes, he took me somewhere I haven't been," Tszyu said.

"It's definitely something I can learn from and train to get better.

'All my respect to Dwight, he's one hell of a competitor."

Ritchie was bothered by a cut near his left eye, which opened up in the third round, but he refused to use that as an excuse.

"I don't want to take anything away from Tim, he fought a great fight," Ritchie said.

Tszyu remains interested in a fight with former WBO welterweight champion Horn, who was commentating at ringside.

However, Horn will compete at middleweight when he takes Michael Zerafa in Bendigo on August 31 and there's no guarantee he will drop down a division after that contest to take on Tszyu.

Another fighter still boasting an unbeaten professional record after Wednesday is Carlton AFLW star Tayla Harris.

After a quiet first round, Harris (5-0-1, 1 KO) cut loose in the second and a series of big shots prompted a stoppage by debutante Renee Gartner.
