Tony Bellew is 8/5 to win inside six rounds as he prepares for Saturday's WBC world cruiserweight title defence against BJ Flores in Liverpool.
Bellew, 33, experienced the highlight of his career so far in his last fight in May when he knocked out Ilunga Makabu at the Goodison Park home of his beloved Everton to become a world champion for the first time.
As the Liverpudlian acknowledged at the time, a long-held dream of his has been achieved but he insists he is not lacking motivation for the fight at the Echo Arena.
He said: “I understand if people are asking if I am struggling to get up for this. But when I step between the ropes I fight for one thing, and that is my life. And I can't back down.
“There is a reason you see me get off the floor and carry on in fights, a reason why I just keep going and going and going. It is because I have not got a switch inside me which says I have had enough.
“All I am thinking about is me and him - and I'm thinking I'm going to punch him from pillar to post.”
Bellew (27-2-1, 17 KOs) is 1/2 for another knockout and is 1/17 for the win, with Flores 7/1 to claim his maiden world title at the age of 37.
The American (32-2-1, 20 KOs) said: “It is going to mean a lot, and it is going to give a lot of people hope. It has been a dream of mine my entire life to win a world title, and so many people give up on their dreams and say 'I can't do this, I'm not good enough'. I feel like it could be an inspiration to a lot of people.
“It doesn't matter how old you are - if you follow your dreams, work hard enough and believe in yourself, you'll give yourself the opportunity to do so.”
The fight is 7/4 to go the distance, with Bellew 2/1 to win on points and Flores 20/1.
Saturday's event also sees Hull's Olympic gold medallist Luke Campbell as the 1/6 favourite when he fights Liverpool-born Derry Mathews (4/1) in a lightweight contest.
