David Haye accepts that beating Dereck Chisora in Saturday's grudge match at Upton Park will fail to enhance his legacy.
The credibility Haye lost with his wide points defeat by Wladimir Klitschko 12 months ago - which he subsequently partially blamed on a broken little toe - will be shattered beyond repair should he lose to Chisora.
Starting as a strong favourite, the 31-year-old from Bermondsey is facing a less experienced opponent who has lost his last three fights.
Before tarnishing his reputation against Klitschko, Haye admitted it was his "career-defining fight, the one I'll be remembered for in years to come".
And while crushing Chisora - a man he hates - will prove satisfying following their disgraceful brawl in Munich five months ago, he knows history will be indifferent to the victory.
"Beating Chisora won't add to my legacy," he said.
"In 50 years time when people look back at my career they won't see this fight and think Dereck Chisora was a great fight and look what David did to him.
"Chisora doesn't have any titles and has been coming off three losses.
"It's a fight for the night, simply because I beat him up at a press conference a few months ago.
"There is no doubt this fight is happening because of the brawl we had in Germany.
"Without that he'd have been another anonymous Klitschko victim. After I knock him out, he'll go back to being a nobody.
"He's going to come out looking for a tear up, which is the perfect style for me.
"If he goes out and does what he normally does, he's getting chinned.
"I'm healthy, strong, fit and fast. I'm looking forward to doing some damage.
"This could be my last fight if the Vitali Klitschko fight doesn't happen. I want to go out with a bang and do some damage."
The British rivals faced each other for the final time before their showdown at Wednesday's head-to-head press conference in Camden, north London.
Separated by a steel fence and flanked by security guards - measures deemed necessary having trading punches in Munich - the meeting passed without incident.
Chisora, the bottom half of his face masked by a Union Jack bandana, appeared more relaxed as insults were swapped across the metal barrier.
A string of outrageous incidents, including slapping Vitali Klitschko before February's weigh in and later spitting water into the face of Wladimir, has earned the 28-year-old from Finchley notoriety that he was happy to trade on.
"David said it's going to be the best ever Hayemaker in the ring and that's great for me because I'm going to be the craziest I ever came into the ring anyway," he said.
"I'm going to go crazy on you David. I feel like John Wayne and I go crazy when I have this on (referring to his bandana)."
Objections have been raised to the fact Saturday's adversaries are profiting from what happened in Munich, despite the universal disapproval that greeted their behaviour that night.
Haye, however, is unrepentant and has a simple message for those opposed to the staging of Saturday's clash.
"If you're so disappointed, stop looking at it on YouTube," he said.
"It's had 20million hits. People are looking at it. If I'm disappointed in something, I'm not going to keep looking at it."
