David Haye fears his explosive victory over Dereck Chisora in a therapeutic night for British boxing has ended any hope of facing Vitali Klitschko.
The five-month feud started by the Londoners' shameful brawl in Munich concluded with a warm embrace of mutual respect following five action-packed rounds at Upton Park.
A vicious left hook effectively ended Chisora's brave assault and will have given Klitschko plenty to ponder as he considers a showdown that to date has proved frustratingly difficult to arrange.
It was an explosive performance from Haye that helped blur the memories of his lamentable loss to Wladimir Klitschko a year ago, but the 31-year-old is concerned it may have been "too good".
Chisora, who troubled Vitali across 12 rounds in February before grappling with Haye at the ensuing post-fight press conference, predicts defeat for the Ukrainian.
"Vitali doesn't fight any more, he doesn't have any power. I believe David will do amazingly and will probably win it," Chisora said.
For the first time in his career Chisora was sent tumbling to the canvas, the victim of a left hook-right hand combination.
The 28-year-old staggered to his feet and continued, but Haye's finishing was clinical with a barrage of punches ending the evening.
All three scorecards had him ahead - 39-37, 39-37, 40-36 - at the time of the stoppage, but Chisora had pushed him hard and provided several worrying moments.
