Former WBO welterweight champion Jeff Horn plans to take a few weeks off to recover from the tough rematch win over middleweight contender Michael Zerafa.

Horn's promoter, Dean Lonergan, wants the boxer to begin training for another big fight.

The obvious big option in 2020 is undefeated rising star Tim Tszyu (15-0), son of Hall of Famer and former unified champion Kostya Tszyu.

Lonergan believes Tszyu is not close to being ready for a fighter like Horn.

Based on the gutsy win over Zerafa, Lonergan predicts Horn would demolish Tszyu in a one-sided fight.

But Tszyu has been calling out Horn for some time and he's willing to fight him next.

“Not a chance (he could beat Jeff in his next fight),” Lonergan said to The Australian. “Jeff Horn, on that performance, destroys Tim Tszyu and I’ll also say that Michael Zerafa, on that performance and his last performance, destroys Tim Tszyu.

“It’s not even the same conversation. But at the end of the day, we’ll take the fight, Jeff will make a lot of money for knocking him the f--- out. After Jeff Horn lost to Crawford, Tim Tszyu said ‘get me that fight’. Are you kidding me? One is the best in the world and one that has beaten a few Australian club fighters. Seriously?

“Jeff Horn verses Tim Tszyu — it is no war, it is a trouncing. We will have a look around at the opportunities. I don’t want to fight at middleweight ever again. We all agree that light middleweight is where he should be. I would like to see Jeff, as long as he is up for it … fighting again in April. If he is going to fight, he gets back training at the end of January and we fight in April. We go into full-on camp on February 1.

“At his age, he doesn’t need hit outs, we need fights to be meaningful. Whether that is to be the number one Australian at light middleweight or a world champion at light middleweight, it’s up to what Jeff wants. We need to put fights in front of Jeff that motivate him. The first Zerafa fight didn’t … we ended up with a fat welterweight and he lost. This one really motivated him and he won.”
