Danny Green claims Krzysztof Wlodarczyk will provide the biggest challenge of his boxing career when he attempts to capture the WBC cruiserweight world title at Perth's Challenge Stadium on Wednesday night. Both boxers made weight, with Wlodarczyk weighing in close to the division limit 90.3 kg [199-pounds] and Green being lighter at 89.5 kg [197.3-pounds].

Wlodarczyk will put his title on the line for the third occasion since winning the vacant belt in May 2010, but it will be the first time he has done so outside Poland.

The 30-year-old Pole hasn't lost since his defeat to American Steve Cunningham for the IBF cruiserweight title in May 2007 and boasts an impressive record of 45-2-1 (32 knockouts), but Green is confident heading into the hometown bout.

He claims to have learned some harsh lessons from his loss in July to Antonio Tarver, and has focused solely on his training for the fight, with the promotion left to others.

"It's a difficult contest because he's an animal and a big guy who is a knockout puncher, and is a two-time world champion," Green said at Tuesday's weigh-in.

"It's the most difficult fight of my career but it's one that I'm looking forward to a lot."

"Wlodarczyk is a very imposing figure and opponent, and a current world champion, so I just have to be cool and do my job.

"We are very confident but he is very confident himself too, so it's going to be a war when you have two guys very confident of victory with a bit of ticker."

Not normally one for predictions, Green couldn't resist on fight eve.

He hopes victory will silence those who suggested he should have retired after his disappointing loss four months ago to Tarver in Sydney.

"I predict that I'm going to be the new WBC world champion," Green said.

"You lose a fight and everyone expects you to walk away. It's a strange and fickle sport like that when it comes to people and their opinions.

"I had won 10 on a trot and now I'm fighting the best cruiserweight in the world so I think that the merit of me still being here is worthy."

Wlodarczyk, though, has expressed a desire to unite the world's cruiserweight titles after his fight with Green so, to be a chance of doing that, he has to be victorious in Perth.

"There is 12 rounds of boxing and you never know what will happen," Wlodarczyk said through an interpreter on Tuesday at the weigh-in.

"My prediction is that I don't know if this fight will be finished by knockout or points, but I'm sure that I will still have the WBC cruiserweight championship."
