IBF super-middleweight titlist Froch seldom has a good word to say about his British contemporaries, and yet branded Cleverly and his super-middleweight rival George Groves ‘disloyal’ for working out with the Dane, whom Froch fights on Saturday.
Cleverly hit back in an interview with Steve Lillis, saying he doesn’t owe the Nottingham man anything.
"If anything, Froch is being hypocritical because he was advising Kessler how to beat Brian Magee last year," said WBO light-heavyweight champion Cleverly.
"Kessler asked me to go out and spar in Copenhagen. I decided it would be a great experience to go and work with someone of Mikkel's calibre.
"I've got no issue working with Mikkel because I don't owe Carl Froch anything. In fact, we are rivals.
"Why should I have remorse? I don't even know Carl and we have never socialised."
Despite the disagreement, Cleverly feels Froch will win this rematch at the O2 Arena despite Kessler winning the first bout between the two.
"It is going to be very tough for Mikkel,” Cleverly said. "He is coming up against Froch who has good momentum behind him and will give it everything because he wants this fight bad."
The Welshman's promoter Frank Warren has previously offered Froch the chance to move up to 175lb and challenge Cleverly in a British superfight, but Cleverly does not see that happening.
"Froch has said a few disrespectful things about me in the past and always talked around the chances of us meeting in the ring,” he explained. “It is quite clear he doesn't fancy the fight with me. I feel I would give him a boxing lesson."
