Catenaccio

Catenaccio (Italian pronunciation: [kateˈnattʃo]) or The Chain is a tactical system in football with a strong emphasis on defence. In Italian, catenaccio means "door-bolt", which implies a highly organised and effective backline defence focused on nullifying opponents' attacks and preventing goal-scoring opportunities.

Italian Catenaccio was influenced by the verrou (also "doorbolt/chain" in French) system invented by Austrian coach Karl Rappan. As coach of Switzerland in the 1930s and 1940s, Rappan played a defensive sweeper called the verrouilleur, positioned just ahead of the goalkeeper. Rappan's verrou system, proposed in 1932, when he was coach of Servette, was implemented with four fixed defenders, playing a strict man-to-man marking system, plus a playmaker in the middle of the field who played the ball together with two midfield wings.

In the 1950s, Nereo Rocco's Padova pioneered catenaccio in Italy where it would be used again by the Internazionale team of the early 1960s.

Rocco's tactic, often referred to as the real Catenaccio, was shown first in 1947 with Triestina: the most common mode of operation was a 1–3–3–3 formation with a strictly defensive team approach. With catenaccio, Triestina finished the Serie A tournament in a surprising second place. Some variations include 1–4–4–1 and 1–4–3–2 formations.

The key innovation of Catenaccio was the introduction of the role of a libero ("free") defender, also called "sweeper", who was positioned behind a line of three defenders. The sweeper's role was to recover loose balls, nullify the opponent's striker and double-mark when necessary. Another important innovation was the counter-attack, mainly based on long passes from the defence.

In Helenio Herrera's version in the 1960s, four man-marking defenders were tightly assigned to the opposing attackers while an extra player, the sweeper, would pick up any loose ball that escaped the coverage of the defenders. The emphasis of this system in Italian football spawned the rise of many top Italian defenders who became known for their hard-tackling, ruthless defending. However, despite the defensive connotations, Herrera claimed shortly before his death that the system was more attacking than people remembered, saying 'the problem is that most of the people who copied me copied me wrongly. They forgot to include the attacking principles that my Catenaccio included. I had Picchi as a sweeper, yes, but I also had Facchetti, the first full back to score as many goals as a forward.' Indeed, although his Grande Inter side were known primarily for their defensive strength, they were equally renowned for their ability to score goals with few touches from fast, sudden counter-attacks, due to Herrera's innovative use of attacking, overlapping full-backs.
