Anthony Mundine has called out Jeff Horn after knocking out Tommy Browne.
42-year-old Mundine put Browne down in the second round, flooring him with a left to the head on the bell.
The KO won him the vacant WBO Oriental middleweight title.
He then called out Horn, who holds the WBO welterweight title.
"I think the boxing public and the whole of Australia would love that domestic fight showdown," Mundine said.
"He can fight Crawford after me. I think we all want that — let's get it done.
"I whipped Danny Green and now I'll whip Jeff Horn."
Horn is looking to defend his title against American fighter Terence Crawford.
