Carl Frampton beat Hugo Cazares in the second round of their super bantamweight WBC title eliminator in Belfast.
The 27-year-old Northern Irishman, ranked number two overall in the weight division, put Mexican Cazares on the canvas with a left hook in the second round at the Odyssey Arena.
Cazares, 36, appeared to mistime the 10-count before getting up and therefore missed out on a title shot against his countryman and incumbent WBC champion Leo Santa Cruz, who is unbeaten in 28 fights.
"We are going to make an outstanding proposal to Santa Cruz financially and hopefully he will come over to Belfast," Frampton's manager Barry McGuigan told BBC Sport.
"The sooner we can get it on the better.
"He has got morals and I believe he genuinely wants to fight Carl. It is all about sitting down and hammering out the deal."
Frampton reflected on the left hook that put Cazares down, saying: "That was a big shot that hurt him and it shows the power I have.
"I just threw it and it landed and that was game over.
"The support has been fantastic. I have the loudest bunch of supporters in Europe without doubt."
On the prospect of facing Santa Cruz, Frampton added: "He wants to be in blockbuster fights and me against him would be huge.
"It is the most exciting fight out there right now and I think he will want it even more now."
