Scotland assistant coach, Pieter de Villiers joins Chris and Caroline on this week's episode of the Official Scottish Rugby Podcast to chat all things scrums.

Ahead of this weekend's Community Game Conference at Scottish Gas Murrayfield, where Pieter is hosting two scrum workshops, he speaks about the link between the physical, tactical and physiological aspects of scrummaging.

He also discusses the value of the scrum, interaction with refs and looks ahead to this summer's tour to North and South America.
