The modern-day flanker is an all-round athlete, combing speed, power and skill into one position.
The openside flanker is usually a slightly different build from their partner, the blindside flanker.
They are smaller in size, making them more mobile around the pitch.
One of their main roles is to win ball from the opposition, which means battling for possession at rucks and breakdowns.
The openside flanker will often be the player with the responsibility to mark the other side's fly-half.
They do this by quickly closing them down, reducing the time they have to kick or pass.
Because of their high tackle count, flankers are always involved in rucks or mauls either at the bottom or making the big drives.
