The goal-keeper is a position in association football. It is the most specialised position in the sport. The goalkeeper's main role is to stop the opposing team from scoring. This is accomplished by having the goalkeeper move into the trajectory of the ball to either catch it or direct it further from the vicinity of the goal line. Within the penalty area goalkeepers are allowed to use their hands, giving them the sole rights on the field to handle the ball. The goalkeeper is indicated by wearing a different coloured kit from their teammates and opposition.

A midfielder is an outfield position in association football. Midfielders may play an exclusively defensive role, breaking up attacks, and are in that case known as defensive midfielders. As central midfielders often go across boundaries, with mobility and passing ability, they are often referred to as deep-lying midfielders, play-makers, box-to-box midfielders, or holding midfielders. There are also attacking midfielders with limited defensive assignments.

Forwards are outfield positions in an association football team who play the furthest up the pitch and are therefore most responsible for scoring goals as well as assisting them. As with any attacking player, the role of the forward relies heavily on being able to create space for attack.
