David Haye has insisted that he is still confident that a fight with Vitali Klitschko can be arranged this year.
The British former world champion says that although he has not heard from Klitschko's team, everything has already been agreed.
The 32-year-old did admit that if the fight did not happen this summer then it may never happen.
"We haven't heard a word from his people since Vitali fought [Dereck] Chisora [in February 2012]," Haye told Sky Sports.
"Everything is sort of agreed, it's just a matter of when and where. I have said I am more than happy to go and fight in Germany like I did before [against Vitali's brother Wladimir]. I expect the fight to be in Germany.
"If it's not happened by the summer then [I must] accept the fact that the fight is never happening and move on."
Haye came out of retirement to beat Chisora in July last year and has always insisted that if he can not fight one of the Klitschko brothers he will continue his retirement.
