Haye and Chisora notoriously traded blows at a press conference in the aftermath of Chisora's loss to Vitali Klitschko in February.
The British rivals, separated by a steal fence and flanked by security guards, came head to head in the final press conference before Saturday's showdown.
Haye opened hostilities by declaring he would knock out Chisora in the opening rounds, but his opponent insisted he would fight fire with fire.
"I'm going to be the craziest I've been when I come into the ring," Chisora said. "Everything has gone well for me, I have no injuries and it's going to be a great fight."
Haye insisted: "Dereck's getting knocked out quick. The harder he comes the quicker he gets KO'd. My training has been good. I'm healthy, fit and fast.
"This training camp has been one of the first I've been able to do everything we planned because nothing has broken down.
"It's a situation I've never been in before and I can feel the difference.
"My sparring partners have felt the difference as well. Unfortunately for Dereck he's fighting the best ever Hayemaker."
Puerto Rican Luis Pabon has been confirmed as the referee for the fight.
