Calzaghe, 43, has long been retired since his days as a super middleweight God, although never crossed paths with Froch despite bad blood being evident between them from the off.
The pair have exchanged angry words via social media, with Froch even claiming he was blocked by Calzaghe as their disagreements continue over who would have come out on top.
If they’d have met in the ring, Calzaghe was in no doubt about the result when addressing their conflict this week.
“We had a little bit of banter on Twitter which was funny. He’s not blocked,” Calzaghe told Sky Sports.
“I haven’t got a relationship with him. It’s irrelevant. I retired six years ago. It would have been a great fight, a big money fight, and I would have demolished him.
“If there was one fight I wish I had fought, it would have been Carl Froch. At the time I had bigger and better things, fighting Mikkel Kessler for the undisputed championship of the world, and then I stepped up to light-heavyweight to win a Ring Magazine in America against the then pound-for-pound best (Roy Jones and Bernard Hopkins).
“Speed kills. I make good fighters look ordinary, that’s what I did. Styles make fights, speed kills, simple as that.”
Froch, 37, is contemplating whether to return to ring having regained the world title twice during his career, although Calzaghe is surprised at the level ‘The Cobra’ has managed to reach during his time in the sport.
“I didn’t expect him to have the career that he had. He’s done well, he’s won world titles, lost, come back and won again, lost and come back and won again,” said the Welshman.
