David Haye and Tony Bellew have already clashed in the run-up to their fight
Bellew, 34, has won 28 of his 31 professional fights and holds the WBC and European cruiserweight titles.
But both of his world title fights have been held in his hometown of Liverpool, while David Haye had to go abroad to fight Nikolai Valuev and Wladimir Klitschko.
“I had to fight in final eliminators,” Haye said.

David Haye and Tony Bellew exchanged pushes and punches as their feud raged on
“He’s had things a lot easier in his career,” Haye added.
“I’ve had to fight a lot harder for my accolades.
“I think that will be pretty evident when the first bell rings.”
Tony Bellew called out David Haye from the ring
The bout is one of the most anticipated of the boxing calendar in 2017, primarily because of the ongoing feud between the two fighters.
They clashed and had to be separated after facing off at a promotional press conference.
And their war of words has continued to rage, with Bellew promising to take Haye into ‘deep water’ beyond the fourth round.
But Haye is confident that the bout won’t get near to lasting that long when they meet at the O2 Arena.
“He’s tough, he’s strong but I’ve fought a lot of tough strong guys,” Haye said.
“Everyone said the same thing about John Ruiz but he hadn’t been hit by me and within 20 seconds he was on the seat of his pants.
“I can’t see how [Bellew’s] style can take the power that I produce.
“I physically don’t know how it’s going to happen.”
