David Haye has told talkSPORT he will only step in the ring again if Vitali Klitschko agrees to fight him.
Haye knocked out Dereck Chisora in impressive style at Upton Park on Saturday in their all-British grudge fight.
Haye, however, insists he will walk away from the sport unless he can get a shot at WBC world heavyweight champion Klitschko, ruling out the prospect of meeting Liverpool heavyweight David Price.
"David is a friend of mine and the only fighter I would want to fight is Vitali Klitschko for the heavyweight championship of the world," he told the Alan Brazil Sports Breakfast show.
"I have had my British title fights, I have had my European title fights, I have had my world title fights, I am world level and there is only one guy I can get up for.
"The fight with Dereck Chisora was a one off - it only happened because we had some crazy scuffle in a press conference and the British public got so engulfed in the hype behind that that they demanded to see what would happen if we got in the ring."
