David Haye claims he is ready to realise his destiny after agreeing terms to fight Wladimir Klitschko.
The 30-year-old WBA heavyweight champion has agreed to fight the Ukrainian on either June 25 or July 2 in Germany, in a fight that will unify three of the recognised world belts.
The announcement of the bout comes after months of on-off talks between the two, which has seen them trade verbal blows in the media on countless occasions.
The talking will soon stop, though, and Haye, who will retire when he turns 31 in October, has promised a messy end for Klitschko.
"I always believed we'd one day fight and I'm glad we've cut through the nonsense and put together the most important fight in the heavyweight division," he said.
"This is the match the boxing world has been calling for since I first decided to step into the heavyweight division, and I feel it is my destiny to fight and beat Wladimir Klitschko.
"We are the best two heavyweights in the world and it would have been a travesty for us to have never fought.
"This is an inevitable fight with an inevitable conclusion. Wladimir Klitschko is getting violently knocked out."
Haye has not fought since his third-round stoppage of Audley Harrison last November, and the 34-year-old Klitschko is a far more dangerous opponent than Haye's fellow Londoner.
Haye, though, expects the outcome to be the same.
He added: "I have been chasing this fight since day one, because I know boxing styles and I know which styles I have success against.
"Klitschko is ready-made for me. I eat tall, chinny Eastern European heavyweights for breakfast. Wladimir is a fighter that doesn't like to fight, and he has admitted that fact in the past. Unfortunately for him, I am a fighter that loves nothing more than fighting.
"I have the heart of lion, whereas Wladimir has the heart of a hyena. He cries and squeals and slips into the wilderness at the first sign of danger. Wladimir has proven this over the years, and I'm certain he will want no part of this lion when it finally comes time to go to war."
