Only younger brothers will understand me. We're following in the footsteps of older brothers. You are looking up to your brother. You want to do the same things. You want to do as good as he and do it even better.

I have decided to make a personal message to David Haye. I want him to fight me, to be a man. I wish there will be enough excitement, pressure and courage for David Haye to fight me.
