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

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.

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.

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!

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 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.
