Dubois is associated with trainer Charles for the first meeting with USYK and has created a strong bond in the last two years.
They have worked together in four quarrels and six camps – Dubois was due to facing Joseph Parker in February, but withdrew to two days notice due to illness.
BBC Radio 5 Live Boxing Analyst Steve Buns said, “The relationship is not just in the corner.”
“This is the amount of time when you spend with a fighter in short moments, 10 or 15 minutes later after 10 or 15 minutes after passing through a field and feeding horses in your gym – that’s where you do bondage.”
Charles continued to remind the Dubois about the “second phase” in the first competition – meaning that he wanted a follow -up to the job to prevent UCIC from escape – and this phrase has cropped again in the fight week.
During its 24-fight career, Dubois has thrown an average of 44.3 panches per round, but it increased to 34.1 against usyk.
“Dubois will have to face Usyk at the beginning of maneuver and then suddenly it is four feet to the left and when Dubois has turned UCIC another four legs and hit him three times,” said.
“Dubois will not plan to throw more, but rather to go to more range.
“He is going to warn to use his shoulder and a forerunner to push back. It’s going to be a dirty battle.”
