Coaches do so much research about a referee because they believe refereeing is such a crucial part of the game that the result may hinge on what we say or do. They probably know more about me than I know myself!

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

The objective of a referee is not to get mentioned. I tell a lot of young referees that not being mentioned is king. If you can achieve that, that then it has been a pretty good game.

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

The scrum and the tackle are the two really contentious areas of the game. If you get those two aspects right, most rugby matches will work in your favour.

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.

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.
