Defender

From Wikipedia, the free encyclopedia

In football, a defender is a player whose position of play is behind the midfielders and first and foremost provide support to the goalkeeper. Their primary function is to prevent the opposition from scoring a goal.

There are four types of defender - centre back, full back, wing back and sweeper.

Centre back

The job of the centre backs or central defenders is to stop opposing players, particularly the strikers, from scoring, and to bring the ball out from their penalty area. As their name suggests, they play in a central position. Most teams employ two centre backs, stationed in front of the goalkeeper. There are two main defensive strategies used by centre backs: the zonal defence, where each centre back covers a specific area of the pitch, and man-to-man marking, where each centre back has the job of covering a particular opposition player.

Centre backs are often tall, with good heading and tackling ability. An ability to read the game well is a distinct advantage. Sometimes, particularly in lower grades of football, centre backs concentrate less on ball control and passing, preferring to merely clear the ball in a "safety-first" fashion. However, there is a long tradition of centre backs having more than just rudimentary footballing skill, enabling a more possession-oriented playing style.

The position was formerly referred to as centre half. In the early part of the 20th century, when most teams employed the 2-3-5 formation, the row of three players were called half-backs. As formations evolved, the central player in this trio (the centre half), moved into a more defensive position on the field, taking the name of the position with them. The right and left players in the trio were called the right-half and left-half respectively.

They usually remain in the half of the field that contains the goal they are defending. The taller defenders tend to move forward to the opposing team's penalty box when their team takes corner kicks or free kicks where scoring with one's head is a possibility.

Some of the most well regarded centre backs in today's game include Fabio Cannavaro, Paolo Maldini, Alessandro Nesta, Lucio, Jamie Carragher, John Terry, Lilian Thuram, Carles Puyol, Rio Ferdinand and Roberto Ayala.

[edit] Sweeper/libero

The sweeper is a more versatile type of centre back that "sweeps up" the ball if the opponent manages to breach the defensive line. His or her position is rather more fluid than other defenders who man-mark their designated opponents. Because of this, the position is often referred to as libero (from the Italian word meaning free). The sweeper's ability to read the game is even more vital than for a centre back. A sweeper is sometimes expected to build counter-attacking moves, and as such requires better ball control and passing ability than a typical centre back. However, sweepers are often merely defensive players. For example, the catenaccio system of play, used in Italian football in the 1960s, employed a purely defensive sweeper who only 'roamed' around the back line.

Elías Figueroa, Franz Beckenbauer and Franco Baresi are some of the best ever sweepers in football history, whilst Lucio and Rio Ferdinand would probably serve as the best modern-day examples. Their defending styles are considered to have more of an attacking mentality compared to the modern day centre-back. For instance, Córdoba is known for his ability to read and anticipate the attackers' moves. This allows him to intercept passes and get the ball off the opposition without needing to hurl himself into tackles. Whereas, Ferdinand is known for his ability to intercept opposition's attacking play and run with the ball into the midfield area. This attribute is not often found in English centre-backs, and more known in the Portuguese, Spanish and Italian centre-backs. In modern football, its usage has been fairly restricted, with few clubs in the biggest leagues using the position.

Some observers consider the position of the attack-minded sweeper to have evolved into the position of the defensive midfielder / deep-lying playmaker in modern football (see the article on Midfielders).

[edit] Full back

The full backs take up the wide defensive positions, one on each side of the field. Their main task is to prevent opposition players crossing or cutting the ball back into the penalty area. In some defensive systems, full backs man-mark opponents. Most full backs are also expected to provide an attacking dimension by getting upfield along the wings and providing crosses.

In the traditional 2-3-5 team formation, the two players in the final row of defence before the goalkeeper were referred to as full backs. They were distinguished from the half backs (the "3" in 2-3-5). This formation is little used in the modern game, having been replaced largely by the four-man defence, but the term "full back" lives on — the full backs now occupy the wide positions in the defensive line, with the old centre half [back] doubled-up to fill the central defensive position.

The traditional English full back was a large, strong man who would make substantial use of "hacking" - deliberately kicking the shins of opponents, a practice that was acceptable as legal in Britain but not in other countries, and caused major controversy as the game became increasingly internationalised from the 1950s on. It is now effectively banned everywhere, and it is this in part that has given rise to a different set of defensive roles.

In contrast, the role of the full back often involves an attacking element: to some extent the full backs have replaced the winger and are expected to get forward to deliver crosses from a wide position. The modern full back is usually pacy, strong in the tackle and with good stamina to get up and down the field. Roberto Carlos, Cafu, Philipp Lahm, Gary Neville, Paolo Maldini, Miguel and Gianluca Zambrotta are considered to be some of the best full backs in world football today.

[edit] Wingback

The wingbacks are a modern variation on the full back with heavier emphasis on attack. The name is a portmanteau of "winger" and "back". They are usually employed in a 3-5-2 formation, and could therefore be considered part of the midfield. But they may also be used in a 5-3-2 formation and therefore have a more defensive role.

In the evolution of the modern game, wingbacks are the combination of wingers and fullbacks. As such it is one of the most demanding positions in modern football. Wingbacks are often more adventurous than full backs and are expected to provide width in a team without wingers. A wingback needs to be of exceptional stamina, be able to provide crosses upfield and defend effectively against opponents' attacks down the flanks. Many coaches, including Carlo Ancelotti of A.C. Milan, use wingbacks because he doesn't use wingers in midfield and on the attack.

A defensive midfielder is usually fielded to cover the advances of wingbacks. For example, when Ancelotti fields wingbacks Cafu and Serginho, he usually fields defensive midfielder Gennaro Gattuso as well.

Cafu, Roberto Carlos, Javier Zanetti, Juan Pablo Sorín, Philipp Lahm, Giovanni van Bronckhorst, Gianluca Zambrotta and Fabio Grosso are considered to be the best wingbacks in modern football.
