Israel Adesanya has copped backlash from fans after he taunted the son of Alex Pereira following his UFC victory.

Adesanya turned his attention to Alex Pereira's son after he knocked out his father, and fell to the ground to mock the teenage boy in the audience. 

Sportstalk host D'Arcy Waldegrave says there's no such thing as grace in the UFC, and the sport is inherently aggressive and confrontational.
