Carl Froch believes his career will be defined by Saturday's eagerly awaited world title rematch with George Groves.
A sell-out Wembley crowd of 80,000 will be watching as Nottingham fighter Froch, 36, defends his IBF and WBA super-middleweight titles.
And Froch told BBC Radio Nottingham: "My whole 12-year professional career is basically on the line now and this is how I will be remembered."
Froch won the first bout last November via a contentious ninth-round stoppage.
He added: "It is now for me to put this whole saga to bed and let George Groves crawl back in the hole that he crawled out of seven or eight months ago."
Froch, who has 32 wins (23 KOs) and two defeats from 34 professional fights, said he took 26-year-old Londoner Groves too lightly last time out and has vowed to put that right and use all the pressure and hype positively.
"It's the pressure that everybody puts on me, together with the pressure that I put on myself," Froch said.
"There is pressure from sponsorship obligations, media pressure, pressure from George Groves and his fans, pressure from my fans, pressure from the general public and my family.
"I have the weight of the world on my shoulders, and the pressure I cannot even explain.
"Sometimes I feel like I am going to explode. It is mounting and mounting but I have to keep it together, hold my own, keep my cool and do the business.
"Cometh the hour cometh the man is an old saying that I like. The final hour - until the countdown before the ringwalk - is when I have got to be at my best and physically and mentally at my strongest to go through with it and perform at my optimum."
