After his first season in Puteaux, Herrera rejoined Stade Français for a third time, now as manager. After three seasons with no trophies collected, the club's president opted to sell the club. Herrera moved to Spain, where he spent the next six years with
Real Valladolid,
Atlético Madrid (where he won
La Liga in
1950 and
1951),
Málaga,
Deportivo de La Coruña and
Sevilla, before moving to
Portugal and a two-year tenure with
Lisbon side
Belenenses. Later, returning to Spain, he managed giants
Barcelona, where he won various titles (including La Liga, twice), but several problems, including disagreements between him and star player
Ladislao Kubala, forced him to leave the club in 1960. and Herrera with Inter Milan in 1973 He immediately emigrated to Italy and signed with
Inter Milan (where he was to remain until 1968), winning three
Serie A titles and two
European Cups during his stay with the club, where he used a 5–3–2 formation, and modified a tactic known as the
Verrou (door bolt) – used by
Karl Rappan – to include larger flexibility for counter-attacks; thus, the
Catenaccio system was born. The side was later nicknamed
Grande Inter, due to the club's successes under Herrera's eight–year spell, which saw the team win back–to–back
European Cup titles in
1964 and
1965, as well as three
Serie A titles, and two
Intercontinental Cup titles. During this time he was also coaching
Spain (between 1959 and 1962) and
Italy (1966–67). In 1968, Herrera moved to
Roma, where he became the highest paid manager in the world, with a contract worth an estimated £150,000 per year. He won the
Coppa Italia in his first season, but relations with club president Alvaro Marchini had already soured over the tragic death of his centre-forward
Giuliano Taccola in the team dressing room at an away game against
Cagliari. The following season, 1969–70, erratic results in the league gave Marchini the excuse to sack him. He returned to management for a one-year stint with Inter for the 1973–74 season. Herrera then suffered a heart attack, did not want to coach full-time any more and retired in Venice, where he lived the rest of his life. While inactive between 1974 and 1978, Herrera returned briefly during the end of the decade, managing
Rimini, and finally ending his career with a return to Barcelona for one-and-a-half seasons in 1980 and 1981. ==Manager profile==
