James DeGale has vowed to avenge his 2005 amateur defeat by George Groves on Saturday before moving on "to bigger and better things" and targeting a world title shot.
The pair meet at the O2 Arena in London with DeGale's British super-middleweight title and Groves' Commonwealth belt on the line.
The showdown is the culmination of a six-year feud stemming from their rivalry as amateur stablemates and Groves' victory en route to winning the national ABA championships.
DeGale insists he was "robbed" by the judges back then and the sense of injustice remains, despite him going on to enjoy Olympic glory in 2008.
The 25-year-old said: "I've waited six years for this.
"I was robbed six years ago and this is the story. It all adds up. He beat me as an amateur - well, 'beat me' in inverted commas - but I went to the Olympic Games for our country and won a gold medal.
"Now we're both professionals so let's see who is the best now.
"The last time we shared a ring together it was the amateur James DeGale, the (future) Olympic gold medalist James DeGale. That was me running around the ring, jabbing his head off, fencing him.
"Now this is the professional British champion, ready to roll, ready to take his head off. I can't wait to get in there now.
"I hope he's remembering the old James DeGale and I think he is."
Unbeaten DeGale (10-0, 8KOs) endured a difficult start to life as a professional but has won the critics over and stepped up in class to win the British title from Paul Smith last December.
"If I'm switched on this should be an easy night's work. I can't see it going 12 rounds, seriously.
"This is probably going to be an easier night for me than the Paul Smith fight."
DeGale already has his eye on another step up in class with European and world honours in his sights.
"I'm ranked with three of the major organisations so I'm up there in the top 15 of the world," he said. "So I'm going to scratch this itch on my shoulder and move on to bigger and better things."
DeGale offered one crumb of comfort to his arch-rival, saying Groves (12-0, 10KOs) can recover should he lose.
"He will probably come back from it because he's getting beaten by the golden boy," added DeGale.
Hammersmith native Groves, meanwhile, believes his cocky nemesis is starting to believe his own hype.
"He's in trouble because of the number of lies they have come up with among each other," said the 23-year-old.
"They've said things so many times that they believe them now, such as believing I'm getting knocked out in sparring. Really? Are they banking on that?
"Another example is them highlighting my black eye. Really? Is that all they have? Have they seen me sparring?
"Where has DeGale heard it? From his trainer (Jim McDonnell), his cheerleader, who is just constantly in his ear, telling him how great he is. When he's not."
The grudge match will top the bill in Greenwich alongside Nathan Cleverly's first outing as WBO light-heavyweight champion, when the Welshman defends his title against Poland's Aleksy Kuziemski.
