WBC cruiserweight champion Bellew is convinced the Londoner does not have the stomach for a scrap and has quashed suggestions his opponent could be forced to pull out due to an Achilles problem.
Haye was unsettled during a press conference on Merseyside earlier in the week but remains adamant he will make light work of the Liverpudlian.
The pair have waged a bitter war of words during the build-up to fight night but it is almost time for all of the talking to stop.
There is no belt on the line but personal pride and domestic bragging rights are very much up for grabs. Expect to see fireworks as the pair battle it out in front of an expectant crowd.

WHAT THEY'RE SAYING
David Haye: "Of course he has got under my skin. I would not have taken the fight if he did not get under my skin.
"It has definitely generated the interest and got the fight here but I don't know what he is going to do to survive the first couple of rounds.
"I want to make sure that is it - it's over for him and that he is never fighting again," Haye told Sky Sports.
Tony Bellew: "He can't pull out. He knows if he pulls out, he is a coward.
"I have got in his mind but, ultimately, it is not going to matter what I say. All that matters is this Saturday night.
"He better pray this ends in four rounds because if it doesn’t he is going to be a very sore and embarrassed man," Bellew told Talksport.
