I think first and foremost you have to have a very very clear Vision but where what you are trying to achieve within us. You have to have a definitive strategy of how that you're going to get there. So the component parts of any rugby player is the technical in the Tactical the physical the mental their General lifestyle. You have to understand what will make a player better. So it's easy and again you talk about it from a professional perspective. It's easy to focus on a lot of trivial ideas, which won't make a great difference to the player as opposed to focusing on the things that will make a massive difference. So coming from the world are inhabited for a couple of years in the English Institute of sport where I would see a whole system and put around athletes, but unless a coach understands what each component delivers there's no point having that component as part of your program. You have to make sure The whatever is brought to the player actually adds value to that player and it may mean that you don't have if you don't know how to use nutrition don't use it you nutrition. If you don't know how to use physiotherapy or you have to have us but you have to understand that to be able to make sure it makes that team perform better. And then it's the relationships within the team ultimately though. I think it is a performing team is brought by a Clear Vision a clear identity and style of the way you want to play and then driving values within that group that make people want to work hard for each other and there's very little separates teams other than the great proponent of hard work.
