Froch, the clear favourite with the bookies, will put his WBA and IBF super-middleweight titles on the line but insisted his opponent would run scared, telling Groves he “was in a world of trouble” at a final news conference.
"My experience at top level, my punching power and Groves' inability to take a punch are the reasons he's not going to do what he says he's going to do," he said.
"He's going to run for his life, jab and grab and try to get through it, he's not going to stand and fight.
"I'm really hoping he does have a fight with me because that's exactly what we want. It will be a big, big mistake, he's going to get knocked out.
"You're in a world of trouble, you'll learn some respect. You're getting annihilated on Saturday night, you know it and everyone knows it.
"I can see it in your eyes that you know you're going to get flattened."
But Groves, unbeaten in 19 contests, maintained he will win the fight, adding that Froch is already losing the mental battle.
“Carl thinks I'm going to run but he's wrong, I'm going to come out and meet him in the middle," said Groves.
"I'm ready, this is my time. I couldn't have had a better training camp and I cannot wait for Saturday night, when I will show that this is where I belong.
"He says I'm chinny but I've never been knocked out, I'm unbeaten. He's fighting himself psychologically and he's losing."
Froch has 31 wins from 33 professional fights with his only defeats coming at the hands of Denmark’s Mikkel Kessler and American Andre Ward.
