David Haye's attempts to get under Wladimir Klitschko's skin may have paid off as the build-up to Saturday's showdown intensifies.

The Ukrainian IBF/WBO champion hit out at some of Haye's crude pre-fight goading, condemning the Londoner's "disgraceful and disrespectful" comments about executions, decapitations and ambulances.

Haye's trash talking is two-fold as be bids to promote the fight and also lure his arch-rival into a scrap rather than a boxing match in Hamburg.

The final press conference was unsurprisingly compelling and 30-year-old WBA champion Haye's latest tasteless soundbite appears to have finally got Klitschko angry.

"This is going to be the most brutal execution of a boxer that you've seen for many, many years," he said. "I'm going to go out there and absolutely destroy him, really quickly."

The buzz around the fight continues to increase with around 8,000 Britons heading for Hamburg and Sky Box Office drawing huge interest for a fight which is long overdue.

The pair's rivalry has run for three years - they were due to meet originally in June 2009 - and Haye said:

"A lot of people didn't think it would get this far and thought I would pull out with an injury or something. But I'm here. I'm in tremendous shape and I'm ready to do what I always promised I'd do."
