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.

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.

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

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.
