The Italian football is known for its astute tactics. The Catenaccio (literally a door bolt) is the style of football that has influenced Italian football the most. This defensive style was Introduced by Argentinean coach, Helenio Herrera, while managing Inter Milan in the early 1960s, leading it to dominancy over the Italian and European football. Many Italian teams, including the national team, have copied and elaborated this style. Although football has changed a lot along the years, the influence of this style is still notable in Italian football.
