EIGHT-TIME world champion Roy Jones Junior has stepped up his bid to fight Joe Calzaghe in Wales following Saturday's showdown with Felix Trinidad at Madison Square Garden.

A champion in four different weight divisions from middle to heavyweight, 38-year-old Jones claimed he will knock out Puerto Rican legend Trinidad, 35, in four rounds of their 12-round, 170lb catchweight contest in New York.

Trinidad (42-2, 35KOs) also has Calzaghe in his sights, as does former middleweight champion Jermain Taylor.

Jones told reporters before the final pre-fight press conference his last remaining ambition in the ring is to regain the world super-middleweight title from the undefeated Welshman.

Calzaghe will fight Bernard Hopkins in Las Vegas on April 12 and Jones said he would even travel to Wales to challenge the undisputed super-middleweight champion, despite previously refusing to fight outside his native America in 19-year professional career.

"For all his titles, I'd go,'' Jones said. "I want Calzaghe. 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.

"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.'' The American said making history was a motivating factor for wanting the fight.

Having equalled Bob Fitzsimmons' 1897 achievement of a former middleweight winning a heavyweight title, he would now like to return to the lighter divisions to regain titles.

"The only thing left to accomplish that I've thought about is if I go down and regain the super-middleweight title,'' Jones said.

"Fitzsimmons didn't do that so I'd have one up on him. He can't come back and redo it, and the next person to try and do it will have a hard time to do it all.'' Jones said he was confident Calzaghe would beat Hopkins, adding: "Calzaghe's busy and that's why I know Hopkins won't beat him because Hopkins doesn't have knockout power.

"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.''
