Danny Green rates his next opponent Krzystof Wlodarczyk as the world's best cruiserweight and says victory over the Pole on November 30 will be his greatest boxing accomplishment.
Green will challenge the European fighter for his WBC title at Perth Challenge Stadium.
Wlodarczyk is ranked above Green by a number of boxing websites.
"He's probably the best cruiserweight in the world now that Steve Cunningham has lost his world title, so you have tosay this guy is the best," Green told AAP.
Green said he couldn't believe some pundits were making him the favourite for the contest.
He is looking to re-establish himself as one of the top cruiserweights in the world following his IBO title loss to American veteran Antonio Tarver.
"After my recent devastating loss to Tarver I think if I am victorious in this fight, it will be the best victory of my whole career," Green said.
"Considering whom I'm up against, what I'm up against, who I'm facing and what I've just been through, my age, his age.
"The bigger the risk, the bigger the reward."
Green will have some of his most intense sparring over the next few days before beginning his taper for the fight.
