Defender (association football)

Association football position
In the sport of association football, a defender is an outfield player whose primary coil roles are to stop attacks during the bet on and prevent the opposing team from scoring goals. Centre backs are normally in pairs, with two full-backs to their left field and right, but can come in threes with no full backs.

There are four types of defenders : centre-back, sweeper, full-back, and wing-back. The centre-back and full-back positions are essential in most advanced formations. The sweeper and wing-back roles are more speciate for sealed formations depending on the managers choice of play and adaptation .
A centre-back ( besides known as a cardinal defender or centre-half, as the mod character of the centre-back rise from the centre-half status ) defends in the area directly in front of the goal and tries to prevent opposing players, particularly centre-forwards, from scoring. Centre-backs achieve this by blocking shots, tackling, intercepting passes, contesting headers and marking forwards to discourage the opposing team from passing to them .
The common 4–4–2 geological formation uses two centre-backs. With the ball, centre-backs are broadly expected to make farseeing and pinpoint passes to their teammates, or to kick unaimed long balls down the field. For exercise, a clearance is a long unaimed kick back intended to move the ball a far as possible from the defender ‘s finish. due to the many skills centre-backs are required to possess in the mod game, many successful contemporary central-defensive partnerships have involved pairing a more physical defender with a defender who is quicker, more comfortable in possession and adequate to of playing the musket ball out from the back ; examples of such pairings have included David Luiz, Gary Cahill, John Terry and Ricardo Carvalho with Chelsea, Sergio Ramos, Raphaël Varane or Pepe with Real Madrid, Nemanja Vidić and Rio Ferdinand with Manchester United, or Giorgio Chiellini, Leonardo Bonucci, Andrea Barzagli and Medhi Benatia with Juventus. [ 1 ] [ 2 ] During convention turn, centre-backs are improbable to score goals. however, when their team takes a corner kick or early determined pieces, centre-backs may move ahead to the opponents ‘ punishment sphere ; if the ball is passed in the air towards a crowd of players near the goal, then the heading ability of a centre-back is useful when trying to score. In this case, other defenders or midfielders will temporarily move into the centre-back positions. Some centre-backs have besides been known for their address exempt kicks and potent shots from distance. brazilian defenders David Luiz, Alex, and Naldo have been known for using the cannonball free-kick method acting, which relies more on world power than placement. In the modern game, most teams employ two or three centre-backs in front of the goalkeeper. The 4–2–3–1, 4–3–3, and 4–4–2 formations all use two centre-backs. There are two main defensive strategies used by centre-backs : the zonal defense, where each centre-back covers a specific area of the pitch ; and man-to-man punctuate, where each centre-back has the subcontract of tracking a particular opposition player. In the now disused man–to–man marking systems such as catenaccio, ampere well as the zona mista strategy that later arose from it, there were often at least two types of centre-backs who played aboard one another : at least one man–to–man marking centre-back, known as the stopper, and a unblock defender, which was normally known as the sweeper, or libero, whose tasks included sweeping up balls for teammates and besides initiating attacks. [ 3 ]

Sweeper ( libero ) [edit ]

The sweeper ( or libero ) is a more versatile centre-back who “ sweeps up ” the ball if an adversary manages to breach the defensive line. [ 4 ] [ 5 ] This position is quite more fluent than that of other defenders who man-mark their delegate opponents. Because of this, it is sometimes referred to as libero, which is italian for “ free ”. [ 6 ] [ 7 ] austrian director Karl Rappan is thought to be a pioneer of this character, when he incorporated it into his catenaccio or verrou ( besides “ doorbolt/chain ” in French ) system with swiss club Servette during the 1930s, deciding to move one player from midfield to a position behind the defensive line, as a “ last man ” who would protect the back-line and originate attacks again. [ 8 ] [ 9 ] As bus of Switzerland in the 1930s and 1940s, Rappan played a defensive sweeper called the verrouilleur, positioned good ahead of the goalkeeper. [ 10 ] During his time with soviet club Krylya Sovetov Kuybyshev in the 1940s, Alexander Kuzmich Abramov besides used a actor exchangeable to a carpet sweeper in his defensive tactic known as the Volzhskaya Zashchepka, or the “ Volga Clip. ” Unlike the verrou, his arrangement was not as compromising, and was a exploitation of the WM rather than the 2–3–5, but it besides featured one of the half-backs dropping deep ; this allowed the defensive centre-half to sweep in behind the full-backs. [ 11 ] In Italy, the libero position was popularised by Nereo Rocco ‘s and Helenio Herrera ‘s use of catenaccio. [ 12 ] The current italian term for this position, libero, which is thought to have been coined by Gianni Brera, originated from the original italian description for this function libero da impegni di marcatura ( i.e., “ free from man-marking tasks ” ) ; [ 6 ] [ 7 ] [ 13 ] it was besides known as the “ battitore libero ” ( “ free hitter, ” in italian, i.e. a actor who was given the freedom to intervene after their teammates, if a player had gotten past the defense, to clear the ball away ). [ 11 ] [ 14 ] [ 15 ] [ 16 ] [ 17 ] [ 18 ] In italian football, the libero was normally assigned the number six shirt. [ 8 ] One of the first predecessors of the libero role in Italy was used in the so–called ‘ vianema’ system, a harbinger to catenaccio, which was used by Salernitana during the 1940s. The arrangement originated from an theme that one of the baseball club ‘s players – Antonio Valese – posed to his coach Giuseppe Viani. Viani altered the English WM system – known as the sistema in Italy – by having his centre-half-back retreat into the defensive agate line to act as an extra defender and marker an opposing centre-forward, alternatively leaving his full-back ( which, at the time, was similar to the modern centre-back function ) free to function as what was basically a sweeper, creating a 1–3–3–3 formation ; he occasionally besides used a defender in the centre-forward role, and wearing the act nine shirt, to track back and mark the fight forwards, frankincense freeing up the full-backs form their stigmatize duties. Andrea Schianchi of La Gazzetta dello Sport notes that this change was designed to help smaller teams in Italy, as the man–to–man system often put players directly against one another, favouring the larger and wealthier teams with stronger individual players. [ 19 ] [ 20 ] [ 21 ] [ 22 ]
In Italy, the libero is besides retroactively thought to have evolved from the centre-half -back character in the English WM arrangement, or sistema, which was known as the centromediano metodista function in italian football jargon, ascribable to its association with the metodo system ; in the metodo system, however, the “ metodista ” was given both defensive and creative duties, functioning as both a ball–winner and deep-lying playmaker. Juventus coach Felice Borel used Carlo Parola in the centre-half function, as a actor who would drop second into the defense to mark opposing forwards, but besides start attacks after winning rear possession, in a similar manner to the sweeper, which led to the development of this specify position. [ 23 ] [ 24 ] [ 25 ] [ 26 ] [ 27 ] indeed, Herrera ‘s catenaccio scheme with his Grande Inter side saw him withdraw a player from his team ‘s midfield and alternatively deploy them further-back in defense as a sweeper. [ 28 ]

anterior to Viani, Ottavio Barbieri is besides thought by some pundits to have introduced the carpet sweeper function to italian football during his time as Genoa ‘s coach. Like Viani, he was influenced by Rappan ‘s verrou, and made several alterations to the English WM system or “ sistema ”, which led to his arrangement being described as mezzosistema. His system used a man-marking back-line, with three man-marking defenders and a full-back who was described as a terzino volante ( or vagante, as noted at the time by erstwhile football player and Gazzetta dello Sport journalist Renzo De Vecchi ) ; the latter position was basically a libero, which was later besides used by Viani in his vianema system, and Rocco in his catenaccio system. [ 29 ] [ 30 ] [ 31 ] [ 32 ] Though sweepers may be expected to build counter-attacking moves, and as such require better ball control and passing ability than distinctive centre-backs, their talents are often confined to the defensive kingdom. For case, the catenaccio system of play, used in italian football in the 1960s, much employed a predominantly defensive sweeper who chiefly “ roamed ” around the back line ; according to Schianchi, Ivano Blason is considered to be the beginning true libero in Italy, who – under director Alfredo Foni with Inter and subsequently Nereo Rocco with Padova – would serve as the stopping point man in his team, positioned deep behind the defensive line, and clearing balls away from the penalty area. Armando Picchi was subsequently besides a contribute exponent of the more traditional form of this character in Helenio Herrera ‘s Grande Inter side of the 1960s. [ 11 ] [ 19 ] [ 33 ] [ 34 ] [ 35 ] The more modern libero possesses the defensive qualities of the distinctive libero while being able to expose the confrontation during counterattacks by carrying or play the ball out from the back. [ 36 ] Some sweepers move forward into midfield, and distribute the ball up-field, while others intercept passes and get the ball off the opposition without needing to hurl themselves into tackles. If the sweeper does move up the field to distribute the ball, they will need to make a rapid recovery and run back into their military position. In modern football, its usage has been fairly restricted, with few clubs in the biggest leagues using the situation .
The mod example of this position is most normally believed to have been pioneered by Franz Beckenbauer, and subsequently Gaetano Scirea, Morten Olsen and Elías Figueroa, although they were not the first base players to play this status. aside from the aforesaid Blason and Picchi, earlier proponents besides included Alexandru Apolzan, Velibor Vasović, and Ján Popluhár. [ 36 ] [ 37 ] [ 38 ] [ 39 ] [ 40 ] [ 41 ] [ 42 ] Giorgio Mastropasqua was known for revolutionising the function of the libero in Italy during the 1970s ; under his Ternana director Corrado Viciani, he served as one of the inaugural modern exponents of the position in the country, due to his unique technical characteristics, namely a musician who was not alone tasked with maintain and protecting the back-line, but besides advancing out of the defensive structure into midfield and starting attacking plays with their pass after winning back the musket ball. [ 14 ] [ 43 ] other defenders who have been described as sweepers include Bobby Moore, Franco Baresi, Ronald Koeman, Fernando Hierro, Miodrag Belodedici, Matthias Sammer, and Aldair, due to their ball skills, vision, and hanker passing ability. [ 36 ] [ 37 ] [ 38 ] [ 44 ] Though it is rarely used in modern football, it remains a highly respected and demanding position. late and successful uses of the carpet sweeper include by Otto Rehhagel, Greece ‘s coach, during UEFA Euro 2004. Rehhagel use Traianos Dellas as Greece ‘s sweeper to great success, as Greece became european champions. [ 45 ] [ 46 ] [ 47 ] For Bayer Leverkusen, Bayern Munich and Inter Milan, brazilian international Lúcio adopted the sweeper role besides, but was besides not afraid to travel long distances with the ball, frequently ending up in the opposition ‘s final third. Although this placement has become largely disused in modern football formations, due to the practice of zonal set and the offside trap, sealed players such as Daniele De Rossi, [ 48 ] Leonardo Bonucci, Javi Martínez and David Luiz have played a alike function as a ball-playing cardinal defender in a 3–5–2 or 3–4–3 formation ; in summation to their defensive skills, their proficiency and ball-playing ability allowed them to advance into midfield after winning back monomania, and function as a secondary playmaker for their teams. [ 48 ] [ 49 ] Some goalkeepers, who are comfortable leaving their goalmouth to intercept and clear through balls, and who broadly participate more in play, such as René Higuita, Manuel Neuer, Edwin van five hundred Sar, Fabien Barthez, Marc-André ter Stegen, Bernd Leno and Ederson, among others, have been referred to as sweeper-keepers. [ 50 ] [ 51 ] [ 52 ]
WM formation of the 1920s showing three fullbacks, all in fairly central positions The full-backs ( the left-back and the right-back ) take up the holding wide positions and traditionally stayed in defense at all times, until a set-piece. There is one full-back on each side of the field except in defences with fewer than four players, where there may be no full-backs and rather entirely centre-backs. [ 53 ] In the early decades of football under the 2–3–5 formation, the two full-backs were basically the lapp as mod centre-backs in that they were the concluding line of defense and normally covered opposing forwards in the center of the field. [ 54 ] The by and by 3–2–5 style involved a third gear dedicate defender, causing the forget and right full-backs to occupy across-the-board positions. [ 55 ] Later, the adoption of 4–2–4 with another central defender [ 56 ] led the wide defenders to play even promote over to counteract the opposing wingers and provide corroborate to their own down the flanks, and the position became increasingly specialised for moral force players who could fulfil that function as opposed to the central defenders who remained fairly electrostatic and normally relied on forte, acme and put .
In the modern game, full-backs have taken on a more attack character than was the case traditionally, much overlapping with wingers down the flank. [ 57 ] Wingerless formations, such as the rhombus 4–4–2 formation, demand the full-back to cover considerable crunch up and down the flank. Some of the responsibilities of advanced full-backs include :

Provide a physical obstruction to opposition attacking players by shepherding them towards an area where they exert less influence. They may manoeuvre in a fashion that causes the opponent to cut in towards the centre-back or defensive midfielder with their weaker foot, where they are likely to be dispossessed. Otherwise, jockeying and smart positioning may simply pin back a winger in an area where they are less likely to exert influence.
Making off-the-ball runs into spaces down the channels and supplying crosses into the opposing penalty box.
Throw-ins are often assigned to full-backs.
Marking wingers and other attacking players. Full-backs generally do not commit to challenges in their opponents’ half. However, they aim to quickly dispossess attacking players who have already breached the defensive line with a sliding tackle from the side. Markers must, however, avoid keeping too tight on opponents or risk disrupting the defensive organization.[58]
Maintaining tactical discipline by ensuring other teammates do not overrun the defensive line and inadvertently play an opponent onside.
Providing a passing option down the flank; for instance, by creating opportunities for sequences like one-two passing moves.
In wingerless formations, full-backs need to cover the roles of both wingers and full-backs, although defensive work may be shared with one of the central midfielders.
Additionally, attacking full-backs help to pin both opposition full-backs and wingers deeper in their own half with aggressive attacking intent. Their presence in attack also forces the opposition to withdraw players from central midfield, which the team can seize to its advantage.[59]

due to the physical and technical demands of their toy position, successful full-backs need a wide range of attributes, which make them suited for adaptation to other roles on the pitch. Many of the plot ‘s utility players, who can play in multiple positions on the pitch, are natural full-backs. A rather big example is the real Madrid full-back Sergio Ramos, who has played on the flanks as a full-back and in central defense throughout his career. In the mod game, full-backs much chip in a fairly share of assists with their runs down the flank when the team is on a counter-attack. The more common attributes of full-backs, however, include :
