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.

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.

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.

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 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.

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

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.
