The Nottingham fighter goes head to head with the Dane in a unification bout, with the IBF and WBC super-middleweight titles at stake.
The clash is a rematch of their April 2010 epic and Froch has claimed that the titles will have little relevance to either fighter on the night.
"The titles, really I shouldn't say this, but they don't mean shit," Froch told BoxingNewsOnline.
"The fight is about two warriors getting it on. We are two equally-matched fighters at the top of our game.
"This is the biggest fight of my career. I could happily retire tomorrow but it means more than anything in my career to avenge my defeat.
"I don't know how I'll take this is I get beat. I don't even want to think about the 'L' word, I really don't."
Froch vs. Kessler will take place at the O2 Arena in London.
