A great champion needs a background in amateur boxing, I’'m convinced of that. There you learn everything that you’ll need later as a pro. Someone who’s got more than 400 amateur fights behind him no longer gets nervous before going into the ring and doesn’t lose his nerve during a fight. You know all the boxing styles, you’re prepared for anything, you’ve got the pedigree that you need to be a successful pro.

If you’ve got physical weaknesses, you’ll lose. Nobody who gets cut easily can be a champion, however strong and talented he is. Boxers are trained to see and exploit their opponents’ weaknesses, they hit you on your wounds. Only the strongest survive in this sport.

Now I am ready to set new goals and start a new career for myself outside of the ring.

I am just taking the top fights out there for me. People will get bored seeing me every day knock someone out.

At first I didn’t give a damn to go down in history. I wanted to win. But the more I won, the more I thought about leaving something behind. Yes, it's as important as hell to me. I want to leave something that people will remember me by. Of course, a lot of boxers want to do that. But it's not easy. Take Larry Holmes, he was the big man after Muhammad Ali, he wanted to emulate him, but for some reason the public didn’t take him like they did to Ali. I think people won’t fully understand what I contributed to the sport for years.

I always ask myself why old heavyweights come back, but I plan to stay out of the ring.

I am going to have one Klitschko for breakfast and one Klitschko for lunch.
