Carl Froch insists his personal dislike of George Groves will not distract him as he defends his WBA and IBF world super-middleweight titles against the Londoner on November 23.
Promoting the fight in Manchester on Tuesday, Froch said he has "no respect for George Groves as a person" and delivered a string of verbal barbs at his opponent as they posed for photographs.
But he said: "I don't get involved in personal vendettas. When I get in the ring, I'm fighting a guy with two arms and two legs and a jaw.
"I'm looking at the jaw to try and incapacitate it and I'm looking at the gloves to keep out the way of them.
"It doesn't matter who I'm in with, I don't even look the guy in the eyes really. I look at the chest and the gloves and I move myself around the ring."
Groves suggested Froch had "fallen apart" in past fights and added: "I genuinely feel that after Froch's career to date and the things I've seen, I have the tools to beat him."
"I've been confident for a while now that if we did box, I would beat him.
"I can't wait to get in there and expose the things I believe I see in Carl Froch that no one else yet has done."
Froch has lost to Andre Ward and Mikkel Kessler in his career, though he avenged the latter defeat in a rematch with the Dane in May.
And he said: "I'm not getting wrapped up in any animosity. He's (Groves) trying to get something going, saying he's seen me fall apart or something.
"I've only ever lost to one guy and that's Andre Ward, and I didn't fall apart. I was trying to chin him.
"I was throwing big shots and the guy was quick, he was ducking them and he was holding and hitting, he's very cute and clever at what he does."
While 36-year-old Froch pledged to take the unbeaten Groves seriously at the Phones4U Arena and admitted defeat could be "curtains" for his career, he remains supremely confident of victory.
"To be fighting someone from Britain and defending my world titles, it's exciting because it's different," he said.
"Even though I don't think George Groves is at the races in this fight, he's still an unbeaten fighter and I'll treat the fight with respect.
"He's knocked out 15 of his 19 wins so he's demonstrated good punching power.
"I'm still going to get in there and do what I do best, perform to my best ability, and that's going to be enough to just whitewash him, simple as that."
