Carl Froch says he is determined to "put the record straight" when he faces Mikkel Kessler on Saturday night.
The Nottingham fighter was beaten on points in 2010 when he fought Kessler in Denmark, but is determined to exact revenge at the O2 Arena and add the WBA super-middleweight title to his IBF belt.
Froch said: "Since the first fight with Mikkel Kessler I've been thinking about the fight and dwelling on the fact that I lost. I know I won my WBC title back in my next fight against Arthur Abraham, but I didn't beat Kessler.
"For the past 14 weeks I haven't taken my foot off the gas. The rematch with Kessler has been in the back of my mind.
"I want to get revenge and get myself back to the position where I can say that night in Denmark should never have happened.
"To be given the opportunity to set the record straight in front of 18,000 fans in this fantastic venue, it doesn't get any bigger.
"To be involved in a fight of this magnitude against a fighter of the calibre of Mikkel Kessler; the hairs on the back of my neck are almost standing up."
Froch revealed he had a 10-round fight with Tony Bellew earlier this week and feels it was hugely beneficial to his preparations.
"We shut the gym, locked the doors; there was just Tony and myself and our trainers," he said.
"Obviously we had big gloves and headguards on but I feel like I've already boxed. I'm so sharp and strong; I'll show you on 25 May how well the camp has gone.
"Since turning professional I've boxed in 13 world title fights, but none as big as this. This is the pinnacle of my career.
"I cannot wait to get in the ring and do a job on Mikkel Kessler. I owe him one. It's time for me to set the record straight. I'm going to leave absolutely everything in the ring."
