I love fighting. I don't know what it is in me, whether it's a sickness or a gene, but I just love standing in front of another fighter and going for it: they can hurt me, and I can hurt them.
Usyk is less of a puncher than Lomachenko but comes with just as high a work rate, so Usyk has to take some to give some to be exciting, whereas Lomachenko has genuine power, and he can stop fighters with that power.
What people have to realise is that it's not the fights that are really hard; it is the training camps. It's living away from home for 12 weeks. It's sparring with guys who are told they will get £1,000 cash if they can drop me.
I know what I am getting into with heavyweights. Not one of them can dictate against me because, firstly, they don't have feet fast enough. Secondly, while there are far better athletes and stronger fighters than me, even some who are quicker, they don't have the ring IQ I have. It allows me to dictate.
Stylistically, Tommy Hearns is much better than Marvin Hagler - his technique and punching were better - but he just couldn't do it. He couldn't beat Marvin Hagler, and it's because styles make fights.
I'm the best heavyweight outside the world champions, and let's not forget that.
I had a headache for four days after the first Haye fight. I didn't tell anyone, I just went to bed and thought it would go. But for four days it remained. Then I got my brain scan before the second fight, and I was worried when I went for it.
