That's the view of Dean Lonergan, the promoter of World Boxing Organisation welterweight champion Jeff Horn, who questions "whether Mundine has got the balls to step up to the plate" and face the undefeated ANBF Australian and Australasian middleweight champion.

Toussaint (13-0) is a star on the rise in Australian boxing and the humble Canberran's camp says he would take the fight "in a heartbeat".

Toussaint has been backed by Australian boxing great Danny Geale to win a world title and Lonergan believes he can after he captured the Australasian crown over Gunnar Jackson - a man that went the distance with Mundine (48-8) and WBA regular world champion Ryoto Murata.

"Dave Toussaint is one of the best up and comers in Australia. He is an outstanding talent with the potential to do something very similar to what Jeff Horn has done," Lonergan said.

"I think if Toussaint was to fight Mundine, it would be one-way traffic and Mundine would get knocked out. Whether Mundine has got the balls to step up to the plate, I don’t know, to be honest.

"[Toussaint's promoter] Nick Boutzos has got the capability of putting on a big fight down there and I’d love to see a fight like that happen in Canberra."

Lonergan has a simple answer as to why a southpaw like Toussaint could trouble Mundine. He says the Canberra product is "younger, stronger, fitter, faster".

"Dave has got a lot going for him, his KO percentage is pretty good," Lonergan said.

"I thought David’s performance the other night [against Jackson] was outstanding, and Jackson at best is awkward as all hell, he’s tough.

"Dave has got a bright future and I don’t think Anthony Mundine could go the distance himself with David Toussaint, and that will be reflected in the fact that Mundine probably won’t want to fight him.

"I’ve got real interest in him going forward, he is a great up and coming talent, let’s just wait and see how he goes. I think him versus Mundine will be a great fight and I think Nick Boutzos is the right man to put it on in Canberra."

Toussaint is building up towards his first Australian title defence at an upcoming Capital Fight Show event in August but the chance to take on Mundine would launch him towards bigger things.

The unbeaten 26-year-old has won two Australasian straps - at middleweight and super middleweight - and says Mundine will have to go through the best in Australia for another shot on the world stage.

"I’m the Australian champion so I consider myself the best middleweight in Australia," Toussaint said.

"He’s probably one of the biggest names in Australian boxing and one of the best athletes we’ve seen in a long time. It would be a great opportunity to fight him.

"Styles make fights and I’m tailored to fight against a guy like that and beat him, but anything can happen in a fight.

"It’d be good to fight against a guy of that calibre and that name but we’ll see what happens."

Boutzos says a long, strong southpaw like Toussaint is perfectly suited to take on Mundine in what would be "a great fight for Dave at this stage of his career".

"He’s a hot young prospect on the way up, and with all due respect to Anthony he is probably past his best and on the descent of his career," Boutzos said.

"That’s no knock on him, he has been great for Australian boxing. For us in Canberra that would be a massive fight. We would take that fight in a heartbeat."
