Dereck Chisora is determined to re-establish his credibility as a boxer by upsetting David Haye at Upton Park on Saturday.
The 28-year-old knows the infamous brawl in Munich in February, during which he threatened to shoot and burn Haye, shocked the British public.
Chisora already had a lengthy list of criminal convictions, while his disgraceful behaviour in the build up to the fight with Vitali Klitschko harmed his reputation further.
Amid all the scrutiny of his conduct, the courageous and impressive nature of his points defeat to Klitschko was forgotten.
Chisora believes Satuday is the time to begin repairing some of the damage.
"What happened after the fight took away a lot from my performance," the former British and Commonwealth heavyweight champion said.
"You know everybody painted me with a bad name, but I'll restore my name after this fight.
"I apologise for saying I'll shoot David Haye - I've never even owned a gun - but the rest of it I don't regret."
Chisora starts as underdog against the more-experienced Haye but remains a dangerous opponent, despite entering their clash with three defeats in four contests.
One of those was against Klitschko, another saw him fall victim to a home town decision while challenging Finland's Robert Helenius for the European title.
Haye has his own credibility issues following his lamentable points defeat to Wladimir Klitschko and subsequent attempts to blame the result on suffering a broken little toe.
"If Haye took his beating like a man and admitted he had lost to a great champion, the British people would have been more accepting," Chisora said.
"Don't make excuses about your toe. That was embarrassing for him and his whole family.
"People loved and enjoyed him before that, but then he came out with those excuses about the broken toe.
"I respect David as a fighter, as a man I don't. There are so many things about him that I don't respect as a person, but I can't go into it."
