Middleweight UFC champion Dricus du Plessis says he will employ a "win or die trying" attitude when he defends his crown against Israel Adesanya in Perth.
Adesanya is bidding to become a three-time middleweight world champion at UFC 305 on Sunday, while South African du Plessis is defending his title for the first time.
The pair don't like each other, with Adesanya taking particular offence to du Plessis declaring himself as the first real African champion.
