WBC heavyweight champion Vitali Klitschko wants a rematch with Dereck Chisora to punish the Zimbabwe-born British fighter for his behaviour before and after Saturday's title bout.
"Common sense tells me that I don't need a rematch but my ego, my deep interior, tells me that this man needs to be punished," Klitschko, who won Saturday's fight on a unanimous points decision, told Germany’s Welt newspaper.
"I'd like to knock him out in the ring. The bill has not been paid."
Chisora was involved in a brawl with fellow British heavyweight David Haye at the post-fight news conference in Munich.
He also slapped Klitschko in the face and spat water at the face of his younger brother Vladimir, who holds the WBO, IBF, WBA and IBO crowns, during the pre-fight ceremonies.
"Before our fight, I thought that his behaviour was all part of a show-act," said Klitschko. "Then I realised that he's not playing.
"He hit me in the face before the fight and spat at Vladimir in the ring. Then he got into a fight at the press conference and threatened to shoot someone.
"What kind of person can he be? Unbelievable! I can't grasp it. Everything I have experienced with him is as if I were in a nightmare."
Chisora, 28, has welcomed the opportunity of a rematch, saying he felt that the experience of the 40-year-old Klitschko was the big difference between the two fighters in Munich.
“I'm not going hide behind no excuses, I got beat by experience. I'm gonna keep working hard and we'll get a rematch,” Chisora said on BoxNation.
“I'm very disappointed with myself but you know what I gave a great fight and all the fans at home and all over the world know that I gave a great fight... the only thing that beat me tonight was experience.”
