WBA heavyweight champion is open to the possibility of a rematch with Nikolai Valuev - if the the British champion is unable to get a fight with either of the Klitschko brothers, Wladimir or Vitali. Valuev has an outstanding rematch clause from their 2009 title fight. Haye wants to retire by age 31, with or without the Klitschko brothers. Haye turns 30 in October.

Haye hurt Valuev bad in the final round of their fight. The next time around, he plans to go after Valuev much earlier and thinks he can get a knockout.

"If the Vitali and Wladimir fights don't materialize then there is an option where that could potentially happen [with Valuev]. But if it has to happen, then it has to happen. I believe if I fought him again I'd knock him out this time around. I know I can hurt him and I'd make sure I got to him earlier," Haye told Sky Sports News.

The fights he wants most are against the Klitschko brothers. Haye once again broke down the flaws, that he sees, in both Klitschko brothers.

"The best one for me, in an ideal world, would be either of the Klitschko brothers. Whichever one is available. I know Wladimir has a very effective jab and a good work-rate. But he's very gun-shy - he doesn't like to commit himself. He's shown in many fights when things get hard he finds a way to lose the fight," Haye said.

"The same thing applies with Vitali. When things get tough he pulls out with injuries during a fight. I will find a way to make them boys quit."
