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!

But then southern hemisphere teams are more skilful than their northern hemisphere counterparts, which means games can be easier to referee.

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.

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

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.

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.
