Defender (Soccer)

Defender(British: Defender) Isサ ッ カ ーInpositionone of. The abbreviation isDF.


From the 1920s30 eraUntil then, the position was called Bucks.GoalkeeperLocated in front of, the so-called final line, mainlyDefensePosition to do. The position of DF isCenter backSide backCan be divided into two.

Center back

Center back(British: Center back) Is in the center of the defense linegoalA defender located in front of you. In a broad sense, it is a defender who protects the center including stoppers, sweepers, and liberos, but in a narrow sense, there are two people in the center at the time of 4 backs (2 people in 5 backs).

The main role is to mark the opponent player, mainly the forward player, and mainly prevent the final stage of the opponent's attack and defend the goal. The center back is often left to the line control of the defense. In modern soccer, it may also be required to construct an attack from the defense line. In general, it is a position that requires ball capture ability, long ball processing ability, judgment ability to select positioning and play, and physical ability to compete with the opponent's attacking team, and it is important to be strong in aerial combat. Therefore, tall players often serve, and it is the position with the highest average height. It is a common practice to be placed in front of the opponent's goal in set play in order to utilize that height for attacks. Also, at the end of the game, aiming for a tie or a winning goal, a tactic may be taken to keep it on the front line even in situations other than set pieces, and forcibly create a chance by letting the height and strong physique speak. The operation is often referred to as "power play" in the sense of trying.

When performing a man-to-man mark as a defensive method, the center back playerstopper(ST)WhenSweeper(SW). On the other hand, when performing zone defense (line defense), each player usually plays both roles depending on the situation. The number of stoppers varies depending on the number of defenses, and the number of sweepers is always one.

In modern times, in 4 backs, it is common for the two people in the center to perform zone defense in the center back and play according to the situation without having a specific role. On the other hand, in 2 backs, man-to-man marks are made at the center backs on both sides, and the center back in the center becomes a sweeper, "3 stopper 2 sweeper" is common. Once a representative of JapanPhilippe TroussierIn the flat three that he sought, all three were not in charge of a specific mark and no sweeper was placed, so it can be said that it is a very peculiar tactic for 3 backs.

The center back is a position where there is a high risk of being sent off due to rough play because the victory or defeat of the play in each situation with the opponent player is related to the goal, and the earlier the time zone, the more front line players are replaced. It is a position where it is desirable for a professional player to serve, although it is not as good as a goalkeeper, as he often replenishes a reserve center back.

In England, it is customary to call a center back a center half. This is from the 1930-2-3 formation in the 5sCenter halfThe formation changed to 3-2-5, so the central defender was called the center half as it was.

As the systematic defensive tactics mature, the position of the attack assembly is lowered, and center-back players are also required to have feed ability.


stopper(British: Stopper) Means "a person who blocks", a position where the player of the opponent FW is marked one-on-one and the role is not to let him play freely. High interpersonal ability is required, such as not being overtaken by opponents in dribbling, etc., and not losing in aerial battles. Therefore, a large and strong player is considered to be a suitable role. In addition, the defensive midfielder located in front of the stopper is sometimes called a fore stopper in the sense of "a stopper located in front".


Sweeper,sweeper(British: Sweeper) Is a name that means "cleaner", and does not have a specific mark, and when the stopper player is overtaken, or when the stopper player is competing against the opponent forward, the ball is processed or two rows It is a position to perform covering-related matters such as defense against midfielders who have jumped out of their eyes. In many cases, the formation has one more center back than the number of opponents' center forwards in order to make the most of their role. In the past, it was often located behind the stopper player for covering etc., but now it is important to keep the defense line flat and control the height of the line, along with the stopper in a horizontal row In many cases.


Libero(Yi: Free) Is a name that means "free person" and is a position derived from Sweeper. In many cases, the sweeper system has one more center back than the opponent's attacking team, and among them, the sweeper who does not have a specific mark can be said to be in a position where the number of attackers is reduced. Therefore, from around the 1s, Sweepers who participated in the attack began to appear at the time of the attack. In particular, Sweeper was basically a player who had a high sense of soccer, such as tactical eyes and look-ahead ability, so the number of players who demonstrated that ability even when attacking increased. Until then, it was called Sweeper, which means "cleaner" because it specializes in covering, but when it began to take on the starting point of the attack, it was no longer appropriate to call it by that name, so "defensive It came to be called Libero because it means "a player who is free to participate in attacks".

Libero is from the 1970s to the 1980sGermanyOften seen in, as a pronounFranz BeckenbauerIs especially famous. otherRonald Koeman,Franco Barrage,Gaetano Scirea,Daniel PassarellaEtc. are famous. However, in the 1990s, few liberos participated in the attack. The reason isZone defenseBecame mainstreamOne-on-one defenseThis is because it has become a very rare entity. Although tactical libero has become rare in recent years, a player who has more opportunities to participate in attacks and scores than a general center back is sometimes called libero. The defensive midfielder is also sometimes referred to as the fore-libero, meaning "libero placed in front of the defensive line."

Side back

* Side backJapanglishAnd in English, it ’s about Defender.Full back(British: Full-back), And the full back on the leftLeft back(British: Left-back), Right full backLight back(British: right back).

Side backIs a defender located on both the left and right sides of the 4-back or 5-back. Its main role is to defend on the side, but when attacking, it overtakes the players in the middle stage and runs up to the front line, dribbling and raising the cross ball. In addition to defensive ability, it is also required to have the ability to perform many movements that violently move up and down the pitch, stamina, speed, dribbling technique to break through the side, and a highly accurate kick to raise the cross.

Compared to center backs, which are mainly for physical collision and aerial combat, small players are often in charge because they require running ability and agility, but in recent years, centering from the far side (far side). On the other hand, aerial warfare is also required, so tall side backs are also increasing. In teams that place importance on defense, center back players may be placed in this position and four center back players may be lined up. On the other hand, there are also very aggressive side-back players who are in a defensive position but specialize in offensive ability.

It has a role similar to that of a midfielder wingback player, and many players have high position compatibility and can handle both positions. Also, since both side-back and wing-back players play on the side, it is desirable that the side foot in charge is the dominant foot, such as right-handed on the right side and left-handed on the left side, or both feet can be used in the same way. There are few players who can play on both the left and right sides, which is useful.

1980 eraIt is,Claudio GentileThere were many defensive professional side backs that were similar to center backs that made man-to-man marks for the opponent forwards. But,1990 eraWith the evolution of tactics, sidebacks that take part in attacks while maintaining high defensive ability have become mainstream.Paolo Maldini,Bixente LizarazuEtc. have emerged. And2000 eraAt the expense of defensive abilityWingA sideback specializing in offensive capabilities that is almost as good as it has begun to emerge, representing BrazilRoberto Carlos,KafuThe Brazilian type side back represented by is predominant in the world.2010 eraWith further evolution of tactics, it combines advanced techniques comparable to midfielders.Side midfielderTypes that are also involved in the construction of attacks have begun to appear, such asMarcelo,Daniel Euves,Philip LahmBecame famous.Also at this timeJosep GuardiolaHas come to the forefront by adopting a tactic that allows the sideback to enter the central voluntary position during an attack and play a role in assembling.In Japan, the sideback that has such a role has come to be called "fake sideback" (a translation of Inverted Full-back in English).As a player given the role of fake side backDavid Alaba,Fabian Delph,Alexandre ZinchenkoCan be mentioned[1].
