Carl Froch has said he will respond in kind if Andre Ward attempts to fight dirty in their world-title unification fight in Atlantic City on Saturday.
The Nottingham fighter, who is putting his WBC super-middleweight title on the line, hopes to inflict Ward's first career defeat in the Super Six final.
"He is a very dirty fighter - because he doesn't have the power he tries to use his head and hold," said Froch, 34.
"If he decides to make it dirty, I am happy to oblige and mix it with him."
WBA champion Ward has won all 24 of his fights, but he has secured only 13 of those bouts by knockouts, with his last four victories all coming via the judges' scorecards.
One of those recent wins was over Mikkel Kessler, the only man to have beaten Froch in his professional career.
Kessler complained in the wake of his defeat by Ward that the American had exploited lax refereeing to butt and elbow his way to victory.
But Nottingham's Froch is confident that, whatever Ward's tactics, his own preparations have been good enough to secure a win that would be regarded as an upset by many Stateside observers.
"I have done all the work you need to do. When you have done it all correctly you feel good about yourself," he added.
"The reason I am confident is that I have prepared meticulously. I feel the same as when I beat Arthur Abraham and that was a one-sided shut-out victory."
During their final pre-fight press conference Ward, 27, accused Froch and his camp of showing disrespect to him and his Christian faith.
Froch insists that he preferred to keep "politics and religion" out of the build-up, but believes his opponent, whose nickname is SOG, has become distracted.
"He says he is not arrogant, that he is such a gentleman, but he calls himself the Son of God. You have to be arrogant to call yourself Son of God.
"He let his guard down as to where he is mentally. He was uptight and rattled and there is no need to be. I simply told it like it is and pointed out some of the things he does wrong in the ring."
