As already mentioned, every team must have a goalkeeper. The other 10 players are referred to as 'field players', and are dispersed over the field of play. The field players can be put into three general categories - attackers, defenders and midfielders. While no player (other than the goalkeeper) has an exclusively defined role, the attackers are generally on attack, the defenders are generally on defence, and the midfielders do a bit of both!
