Joe Calzaghe hopes his plans for 2004 will establish him as one of the all-time legends of the ring.
Calzaghe has big plans for 2004
"I'll show everyone how great I am," Calzaghe told BBC Sport Wales.
"I want to go down as one of the greatest fighters this country has ever produced. By the end of the year I want recognition as one of the best pound-for-pound fighters in the world."
The Welshman this week announced his intention to become a two-weight world champion and fight in the States.
"I've dominated the super-middleweight division for six years and beaten all the top US fighters, so now it's time to move on," continued Calzaghe.
"Being inactive last year was frustrating. I'm nearly 32 now and have got no closer to a unification fight.
"It will be great to be the first Welsh fighter to win a world title at two weights, not many British boxers have achieved that.
"But above all I want to stamp my authority on the new division, win a title then go to the States and show them what I can do."
Before his move to light-heavy, Calzaghe must successfully negotiate the 14th defence of his super-middleweight title against Mger Mkrtchyan of Armenia in Cardiff on 21 February.
"Unless I do the job against Mkrtchyan all the plans will go up in smoke," he said.
Tarver is rated the No 1 light-heavy in the States
"But if that goes well I have been promised a fight in Britain in May for the WBO light-heavyweight title, probably against current champion Julio Gonzalez.
"After that I want to fight Antonio Tarver, who gave Roy Jones Jr such a hard time.
"He's rated the No 1 light-heavy in the US, and I'm willing to go to his own backyard to beat the guy.
"If I do that, hopefully I'll get my recognition across the Atlantic."
