(abb. “SW”). A fast & tough player who usually plays just behind the fullbacks, although he is allowed to roam. His job is to cover the space between the fullbacks & the goalkeeper & to stop “breakaways” & “sweep up” the ball or kick long “through balls” out of bounds so the defense has time to recover. Using a sweeper increases your “depth” & field coverage and therefore allows your fullbacks to push up to support your attack. A Sweeper is like a free safety in American football. A good sweeper must be fast & willing to make contact to steal the ball. A Sweeper can be like a coach on the field and can help direct adjustments, since he is usually the deepest field player and in a good position to view the game. The trend with pro teams is to not use a Sweeper but instead to use a “flatback four”, which is 4 Fullbacks playing a zone defense and using a lot of “offside traps”. A Sweeper was originally used to back up man-to-man defenses. However, using a Sweeper can also be used with a “Zone Defense” (i.e., “Spatial Defense”). A great Sweeper who has speed and great coverage skills can allow your Fullbacks to push up to support your attack, even if they aren’t fast, because he will slow down the attack and give your Fullbacks time to recover. However, if you don’t have a great Sweeper, a better alternative for most recreational teams is to use a 3-2-2-3 formation where the FB’s stay deep, as described in “Formations”.
