Carl Froch has promised to give George Groves a "pasting" in their eagerly-awaited super middleweight showdown in Manchester at the weekend, live on Sky Sports Boxing Office.
WBA and IBF champion Froch branded the challenger's intended fight tactics as "ridiculous" and vowed to "shut his mouth".
The pair went face-to-face at the final press conference for Saturday's grudge match at a sold-out Phones 4u Arena.
"I'm feeling good, feeling very confident," Froch told Sky Sports News. "I've seen a chink in George's armour, I don't actually think he believes in what he is saying.
"Up until now, I thought he actually believed in his own stupidity, his own childish remarks and he sort of had a game plan. But he's revealed himself today as being a very worried man and I think the big fight is dawning on him now, it's getting closer and closer.
"He cannot mix it with me at this level, it's impossible. He might have two or three rounds keeping out of the way, jabbing and moving to make it look like a fight,
"But he knows once we start exchanging leather up close and this fight becomes a fight, he's out of his depth and is in serious trouble. I could see that today in his eyes, I could see it in his body language.
"So I'm coming away from this press conference feeling very, very, even more confident than what I was to start with and looking forward even more to giving George Groves a pasting on Saturday night because that's what I do; give people like him a pasting for their cheek."
During the press conference Groves revealed what his plan would be but Froch was unimpressed.
"I thought it was very strange really, because it was quite precise step-by-step diagnostic of what he was going to do. Come out behind the jab and he's going to land a double right hand, then he's going to go into round two and get behind his jab and then he's going to take me on in the centre of the ring.
"It was just ridiculous really to be honest. You can't put that sort of detailed explanation of a fight tactics from round one to round three because you don't know what your opponent is going to do.
"I'm hoping that one of his tactics that he has talked about, to take me on and stand in the middle of the ring and have a fight with me, he stands by and does have a fight with me because that's exactly what I want.
During the face off of between the pair, Froch was the first to turn away but the champion dismissed it as irrelevant.
"Looking away doesn't mean anything, and I'm not being funny but he's got halitosis and it's a condition that's not nice to be stood in front of. That's the reason why I was looking away because I could only bear it for so long.
"I can't wait to flatten George Groves," added Froch. "And when I've done it, I will still tell him what I think of him. I'm not going to shake his hand, give him a kiss and a hug, say don't worry you'll come back and do something in the future when I retire because I don't like the guy.
"And I'm going to show you on Saturday night how much I don't like the guy."
