If at first you don't succeed, get a bigger hammer.

My job is to persuade people to toe the line and play within the laws of the game.

I have three tools at my disposal - my whistle, my body language and my talk. It is a question of how I marry them up to try to get the players around to my way of thinking.

Coaches will do what they can but it doesn't necessarily bother me. You are an international referee for a reason. If things like that are going to ruffle your feathers, don't bother doing the job.

I do my own analysis on the teams I am refereeing. I will know some of the personalities, the players who could be difficult customers in a scrum situation, the ones I am going to have to really work hard on early in the game to get what I want.

I could give 48 penalties in every match if I wanted to. It is a question of sometimes choosing what is - in your own mind - of material importance and what isn't, what might be a crucial potential penalty and what might not be.
