World champion Wladimir Klitschko claims Tyson Fury has changed his attitude and was 'nice and polite' at Friday's weigh-in.
Fury (24-0-KO18) has been very outspoken ahead of challenging the WBA Super, WBO and IBF heavyweight champion this Saturday.
But after weighing in just a pound lighter than the Mancunian, 39-year-old told Sky Sports of the build-up: "Most of the fighters get under their own skin and that's what I saw with Tyson Fury being nasty before and then nice and polite now.
"I'm expecting anything. He's a very flexible fighter – sometimes he fights in southpaw and sometimes he fights regular. Sometimes he makes funny faces during the fight and a lot more, he talks. So I'm prepared for anything and I don't think Tyson himself knows what he's going to do.
"People have studied me for many years and I haven't changed so there are a lot of things to pull out but they're always the same. I wouldn't stay here in a wouldn't do the job professionally.
"A clear victory by knockout is better than on points because then there would be other questions we don't want to hear."
Equally confident of a Klitschko victory is Wladimir's older brother Vitali – a former world heavyweight champion himself and now a politician in their native Ukraine.
He told Sky Sports: "I am very proud to have the strongest brother in the world. Wladimir is the best athlete in the world and breaks so many records. My personal opinion is he's the best heavyweight – the best boxer too.
"He has jabs and combinations. He can beat everyone. Tyson Fury is a good fighter and a good speaker! But Wladimir is the better boxer and we will see that tomorrow night.
"Wladimir and I have had a lot of speakers in our boxing careers. They promise so much and start fighting with words. But boxing is discussion between two gentlemen with fists – not words. That's why Wladimir is a good speaker.
"Wladimir will put in a great performance and everyone is excited."
