The 35-year-old Ukrainian retained his heavyweight titles after a second consecutive win over Anthony Joshua in August and wants to add Fury's WBC crown to his collection early next year.
He said earlier in November he was only interested in fighting him next.
"Well trained, big guy, he knows what to do. It won't be a walk in the park, I know that, but I'm ready," Usyk told Polish news outlet Interia.
"I'll do absolutely anything to win."
Usyk added he never aims for a knockout when he walks into a ring and is happy when he wins by points.
"A knockout is a tough matter for an athlete. I really do not want to take health away from anyone. I am really happy when we both get out of the ring on our own feet," he said.
"Of course I want to win, but I don't want to hurt anyone."
