Under Herrera, Inter enjoyed a highly successful spell, which saw them win three Serie A titles, two European Cups, and two Intercontinental Cups. Manager Ferruccio Valcareggi also used tactics inspired by the Italian "catenaccio" system, which was popularised by Inter manager Herrera during the 1960s, with the Italian national team, employing a sweeper behind two man–marking central defenders and a full-back, as well as a strategy which made use of heavy defending, focussing predominantly on stability, grinding out results while conceding few goals and defending narrow leads; although his tactics were controversial – in particular as during the 1970 World Cup in Mexico, he devised his infamous "staffetta" (relay) policy of playing one of his two star playmakers, Sandro Mazzola and Gianni Rivera, in each half, to avoid offsetting the defensive balance within his team – and not particularly exciting, they proved to be effective. Moreover, although at times he drew criticism in the Italian media over Italy's dull, slow gameplay and lack of goals, Italy also demonstrated their offensive capabilities throughout the tournament, as well as their technical capabilities, which enabled them to conserve energy and cope with the altitude in Mexico. He had a successful spell as Italy's manager, winning UEFA Euro 1968 on home soil, and leading Italy to the 1970 World Cup final. However, in the latter match, Italy suffered a heavy 4–1 defeat to a much more offensive minded and stylish Brazilian side. His team adopted a more attractive playing style in the lead-up to the 1974 World Cup, however, which saw them considered among the favourites to win, but sufferred a surprising first-round elimination in the final tournament. Jock Stein's Celtic defeated the "catenaccio" system in the 1967 European Cup Final with a highly offensive strategy. They beat Herrera's Inter Milan 2–1 on the 25th of May 1967 creating the blue print for Rinus Michels' "total football", a continuation of Stein's free flowing attacking football. "Total Football", which was invented by Dutch manager Rinus Michels in the 1970s, exposed the weaknesses of the "Catenaccio" system. Unlike previous systems, in "Total Football", no out–field player is fixed in their nominal role; anyone can assume in the field the duties of an attacker, a midfielder or a defender, depending on the play. Due to players often switching positions with one another, man-marking strategies, such as "catenaccio", were no longer effective at coping with this fluid system.
