Usyk didn't want anybody to know it before the fight. But you've seen the best version of Usyk so far and Loma-sr was one of the reasons. What a great, I mean GREAT trainer who now trains two of the TOP p4p boxers.
There were speculations about that before the fight from Ukrainian boxing insiders (that there's BIG surprise in Usyk's camp) but they weren't allowed to tell it. It became obvious in the corner though where Loma Sr was telling Usyk what and when to do, Anber was just part of the team, not the head coach, but he did fine job too.
