In 1960, manager Helenio Herrera joined Inter from Barcelona, bringing with him his midfield general Luis Suárez, who won the European Footballer of the Year in the same year for his role in Barcelona's La Liga/Fairs Cup double. He would transform Inter into one of the greatest teams in Europe. He modified a 5–3–2 tactic known as the "Verrou" ("door bolt") which created greater flexibility for counterattacks. The catenaccio system was invented by an Austrian coach, Karl Rappan. Rappan's original system was implemented with four fixed defenders, playing a strict man-to-man marking system, plus a playmaker in the middle of the field who plays the ball together with two midfield wings. Herrera would modify it by adding a fifth defender, the sweeper or libero behind the two centre backs. The sweeper or libero who acted as the free man would deal with any attackers who went through the two centre backs. Inter finished third in the Serie A in his first season, second the next year and first in his third season. Then followed a back-to-back European Cup victory in 1964 and 1965, earning him the title "il Mago" ("the Wizard"). The core of Herrera's team were the attacking fullbacks Tarcisio Burgnich and Giacinto Facchetti, Armando Picchi the sweeper, Suárez the playmaker, Jair the winger, Mario Corso the left midfielder, and Sandro Mazzola, who played on the inside-right.
