"Catenaccio is my art" is a famous quote attributed to Helenio Herrera, an Argentine-French football manager. Catenaccio is a defensive tactic in football that emphasizes preventing the opponent from scoring by forming a solid defensive line and relying on counterattacks. Herrera was a proponent of this tactic and achieved great success with it, notably winning the European Cup twice with Inter Milan in the 1960s.
