David Haye hopeful of facing Wladimir Klitschko
WBA heavyweight champion David Haye hopes to take on WBO and IBF champion Wladimir Klitschko in July after rescheduling his next fight.
Haye claims a mandatory defence against Ruslan Chagaev in May has been cancelled, allowing time for the bout.
The Briton, 30, aims to unify the titles before retiring later this year.
"One way or another my next fight is going to be in July. I am hoping it is going to be against Wladimir Klitschko," he told BBC Sport.
Negotiations over the staging of the fight
stalled in December
with the two camps wrangling over the details of the contest.
But Haye is hopeful that a deal could now be struck, with a 2 July date most likely.
"I believe we are pretty close to agreeing. That's what I believe. Whether we are or not is a whole different matter," he added.
"It seems at this stage that we are ready to do it, so hopefully they are. We should know something more in the next few days."
Haye confirmed that he still intends to take on Wladimir's brother Vitali, the WBC champion, in his final fight before retiring ahead of turning 31 in October.
The Londoner was due to fight Chagaev in May, but the Uzbek has had problems obtaining a boxing licence in Britain as he suffers from hepatitis B.
A potential obstacle to Haye's plans is Wladimir's voluntary defence against
Britain's Derek Chisora on 30 April
- a little over two months before a proposed fight with Haye.
Haye admitted in January that a 2 July meeting was "effectively impossible" unless Wladimir
stepped away from his fight with Chisora.
