David Haye has claimed that he is ready to fight Vitali Klitschko but also admits that a potential rematch with the Ukranian's brother, Wladimir, is possible.
A prospective bout with either brother has been thrown into doubt following Haye's part in a brawl with Dereck Chisora last month.
Haye told Sky Sports News: "I said before my retirement I will only come out of retirement to fight Vitali or Wladmir Klitschko.
"Vitali made a lot of noise the last couple of months saying he wants to fight me but he's gone quiet of late so maybe he doesn't want to do it. If he doesn't then fair enough but if he does then I'll be ready.
"Their people know I'm good to fight at the drop of a hat, I'm always in good shape. If an opportunity arises for me to fight Vitali Klitschko then I'll be ready to do it."
Haye retired from boxing after losing his WBA heavyweight title to Wladimir in Munich last July.
