Bellew has not signed a contract for Usyk fight yet

"My training camp in Sheffield has already begun. We agreed on the terms of the engagement with Usyk, but the contract has not been signed yet. I do not want to talk specifically about this topic, so as not to jinx it, there have been cases in my career when everything broke down at this stage of the organization. I really want to fight with Alexander, because it is a serious challenge and an opportunity for everyone to prove that it's too early to write me off. Yes, there are more attractive financial fights, but here we are talking about something else. I believe that I can not only defeat Usyk but knock him out".
