4-5-1 Sweeper/Flat back

The 4-5-1 line up is seldom a starting line up but rather a formation used later in a game, when a lead or a draw needs to be saved.

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

Stopper (ST): The stopper is responsible for marking the centre forward or centre midfielder of the other team. He also has an important offensive part of distributing the ball to the midfielders.

Left/Right Backs (LB/RB): In the flat back formation, they mark the opponent's forwards and 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. In the flat back version, or in more advanced teams these players are used to carry the ball up the outside with the midfielders, allowing more effective crossing.

Left/Right Midfielders (LM/RM): When playing 4-5-1, outside midfielders need to take charge and demand the ball more than usual. With only one forward, offensive plays have to be played over the outsides, since a 5 men midfield can hardly push up fast enough to support the single forward.
