Costa reveals why Whittaker fight fell through

“Most of the great fights didn’t happen because of a lack of negotiating skills. They need to stop being petty. I think they get it all wrong and that's why most fighters aren't happy with their deals. Not very smart. I'm not the only one in this situation. I remember something like this with Francis Ngannou, Sean O'Malley, Mark Hunt and so on, ”the fighter wrote on Twitter.

Recall that the fight between Costa and Whittaker was supposed to take place on February 11 in Perth.
