This is not a position for the feint-hearted.

The modern number eight has the physical strength of a forward along with the speed and skill of a back.

In short, you've got to be the all-round rugby player.

The number eight is the player who controls the ball at the back of the scrum.

They are also a potential target for the hooker in the line out.

And if that wasn't enough, they are always in the middle of a ruck or maul.

This is a very demanding position for a demanding player.
