Outside Half
The brains of the backs - and the whole team.
The fly-half is probably the most influential player on the pitch.
They are the players who make the big decisions under pressure - run with the ball or kick for territory.
So it goes without saying you need brilliant handling skills and a kicking boot bar none, well anyone in your team at least.
But the thing above all else every world-class fly-half has is a brilliant rugby brain.
You need the ability to break open defences with a clever pass or clear your defensive lines under pressure.
But don't think that's everything - you also need to muck in with the tackles.
As well as being the best kicker in world rugby, Jonny Wilkinson is also considered the best defensive fly-half around.
