In that same BBC Sport interview, Haye said, "We're not going at it to have a pillow fight, we're going at it to have a real, real war."
The championship showdown is now two plus years in the making, with Haye set to fight Wladimir in 2009 but pulled-out unexpectedly shortly before the fight. Later that year, after agreeing to fight his brother Vitali, Haye jumped ship and secretly agreed to fight Nikolai Valuev, taking his WBA title.
Snide comments and trash-talk have been exchanged since then, but it's Haye's actions that mostly have fueled the fire.
The boxer from south London will have to fight his best against the Kiev-born Klitschko, as he is facing a bigger, more experienced fighter than he has ever seen before.
Haye has shown in past fights that he can be at his best in the underdog position, but nonetheless Klitschko's damaged pride in the build-up may prove as further motivation.
Although Klitschko is the favorite, HBO's Jim Lampley says there's no reason to expect the unexpected.
"There' was nothing in Buster Douglas's record that led you to believe he was going to beat Mike Tyson. Cassius Clay was a 7-1 underdog when he first won the heavyweight championship from Sonny Liston in Miami Beach.
"No-one should rule out the possibility that Haye can get something unusual done."
