Joshua takes on Robert Helenius this weekend in a late replacement fight at the O2 Arena after Dillian Whyte failed a drugs test.
AJ was formally trained by ex-professional boxer Robert Garcia, but that partnership only lasted for the second Usyk fight.
Joshua also parted ways with long-term trainer Rob McCracken after his first defeat to Usyk.
