Vitali Klitschko has admitted that he would like to fight Dereck Chisora again, despite beating the British boxer on a unanimous points decision on Saturday.
The 40-year-old Ukrainian is keen to punish Chisora for slapping him during the pre-fight weigh-in.
"In spirit, I have no need for revenge, but my ego tells me that this man deserves real punishment. I want to knock him out in the ring," he told German newspaper Die Welt.
Chisora's future in boxing is currently in doubt following his brawl with fellow Brit David Haye at the weekend.
The 28-year-old has been called to appear in front of the British Boxing Board of Control next month to explain his actions.
