Eight-time world champion Roy Jones Jr has stepped up his attempt to fight Joe Calzaghe in Wales.
Joe Calzaghe is being targeted by Roy Jones Junior
Jones, 38, is facing a high-profile showdown with Felix Trinidad in New York on Saturday and has Calzaghe in his sights after that.
"I want Calzaghe," he said. "If I've got the titles, he has to come and get it but he's got the titles so I have to go and get it.
"It doesn't matter where you fight, you've got to knock him out."
To beat Joe, you're going to have to knock him out
A champion in four different weight divisions from middle to heavyweight, Jones claimed he will knock out Puerto Rican legend Trinidad, 35, in four rounds.
Jones said his last remaining ambition in the ring is to regain the world super-middleweight title from the undefeated Welshman.
Calzaghe, 35, is awaiting confirmation of his April 12 mega-fight in Las Vegas with Bernard Hopkins.
If Jones was to travel to Wales for a fight with Calzaghe, it would be his first outside America in his 19-year professional career.
"The way I see it is that Ricky Hatton came over and fought Floyd Mayweather so it's somebody's turn to go back over there for us, to show that we're impartial, we're fair," he said.
"The only thing left to accomplish that I've thought about is if I go down and regain the super-middleweight title.
"To beat Joe, you're going to have to knock him out. He's far too busy to go 12 rounds and expect to get a decision (against him), especially in Wales.
"That's why I say it doesn't matter where you go to fight him, because you've got to knock him out wherever you go.
"I've got to knock him out but Hopkins doesn't have the power to knock him out.
"That's why he doesn't want to go over there and fight and I don't blame him. But I'll take the gamble."
