4-3-3

Being a rarely used formation, 4-3-3 is not completely defined. The roles of the three forwards, however, are clear. Two should be making runs to the outsides and one either dropping back or waiting for the cross. The midfielders adapt their runs and running paths to those of the forwards. The defence can't count on much support from the midfield.

Left/Right Backs (LB/RB): They are the only real defenders. These players have to be dependable and willing to give up any kind of offensive play.

Left/Right Defenders (LD/RD): They mark the opponent's forwards. These players can be used to carry the ball up the outside with the midfielders, allowing more effective crossing. They also can be sacrificed for a defence with more depth

Midfielders (LC/CM/RC): Distribute the ball among the offenders and try to stop or slow down opposing plays before they get to the defensive line. Also, the attack depends on occasional crosses and long balls down the lines, since the 3 midfielders cannot work the ball forward. These players have to concentrate on holding possession.

Forwards (F1/F2/F3): Runs to the corners feed the attack, and dropping back is usually the only way of getting the ball, due to just 3 midfielders.
