Ahead of this undisputed title clash against Bivol, Beterbiev has been asked if he would fight Canelo Alvarez, but the 39-year-old isn't interested in that.
Speaking on The Stomping Grounds podcast, he said: "When Canelo has a belt in my division, then I'll want to fight him.
Who are the best pound-for-pound boxers right now from Terence Crawford to Oleksandr Usyk and Gervonta Davis?
"Even if that moment comes, I still don't think I'd want to face him. I'm really not interested in a fight with Canelo,"
Meanwhile, Clarke is looking to knock Wardley out in their rematch.
He said: "I'm going in there to do one thing and that's to knock Fabio Wardley out.
"Winning won't be enough for me. I want to put a job on him, but it will be a tough task just like the first one. May the best man win, but I'm backing myself.
"I grew respect for Fabio after that first fight, so I have no trash talk. I think you will see two competitors that just want to get the best out of each other and get their hands raised. Message to the fans is to tune in and enjoy it."
