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.
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, and said: "Beating Chisora won't add to my legacy. 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."
He went on: "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."
