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.
History
The 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, that was highly defensive and was positioned just ahead of the goalkeeper. In the 1950s, Nereo Rocco's Padova pioneered the system in Italy where it would be used again by the Internazionale team of the early 1960s.
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.
