The 4-4-2 formations are probably the most common formations next to the 3-5-2. The sweeper/stopper version has the sweeper as a buffer behind the other three defenders that make up the defensive line. If they make a mistake, the sweeper is there to cleanup the situation.

The flat back four formation is for more advanced teams and requires a high level of fitness and speed. Here is a very basic run through the individual positions within these variations on the same formation (with emphasis on defence):

Sweeper (SW): The sweeper should have a good understanding of the game and be a leader on the field. She controls the defence, staying behind the fullbacks.

Stopper (ST): The stopper is responsible for marking the centre forward or attacking centre midfielder of the opposition.

Centre Backs (CB/CB): In the flat back formation, they mark the opponent's forwards and are the only real defenders. They must be dependable and willing to give up attacking play. They have to be able cover a lot of ground and do so quickly.

Left/Right Backs (LB/RB): They mark the opponent's forwards/attacking midfielders. In the flat back version, or in more advanced teams these players are used to carry the ball up the outside or overlap midfielders, allowing more effective crossing (see Ashley Cole and Lauren for Arsenal).They maybe expected to join the midfield on their side to mark players when the opponents have numbers up in the centre of the pitch (i.e. against a team playing with five across the middle and only one or two up front).

Left/Right Midfielders (LM/RM): They are responsible for supplying crosses for the forwards, they are expected to run with the ball more as they have more space than central midfielders. They may drift into the box as a third forward when the ball is on the opposite flank and they must support their full back when the opposition has possession.

Left /Right Centre Midfielders (LC/RC): Distribute the ball to the forwards and try to stop or slow down opposing plays before they get to the defensive line. They may play side by side or one holding and one pushing forward. Good passing, vision and ball control skills are needed to fill this position.

Forwards (F1/F2): In these very basic formations, the forwards do no special work other than pressurising the opposition's defence. Runs to the corners need to be only occasional, and dropping back to the midfield shouldn't be the primary way of getting the ball.
