David Haye produced an explosive fifth-round stoppage of Dereck Chisora to win a thrilling grudge match that delivered everything it promised.
The hostilities started in Munich five months ago were ended by a stunning left hook that spelt the end of Chisora's challenge at Upton Park.
Haye, who was being outmuscled by his heavier opponent, was in trouble before he delivered the decisive blow that sent his 28-year-old opponent to the canvas.
Chisora beat the count but referee Luis Pabon waved the fight off once he was dropped for a second time, a left hook doing the damage once again.
It was Chisora's first stoppage defeat and a victory that Haye hopes keeps him in contention for a shot at WBC world champion Vitali Klitschko.
"I've sent out a very scary message. I'll be surprised if Vitali Klitschko wants to fight me after that. He will no doubt try to fight some chump and then retire to be a politician," said Haye.
