of the most despicable teams ever to emerge from South America." Zubeldía hired former referees to lecture the team on regulations, so that his players would be able to exploit every loophole in the book. Also, he incorporated tactics that were unheard of at the time, such as playbook drills for free-kicks and corner kicks, the offside trap, and double-marking opponents . The Zubeldía team counted two physicians among its stars: Carlos Bilardo and Raúl Madero graduated from the University of Buenos Aires Faculty of Medicine during their playing days. Juan Ramón Verón was a gifted player who could play left wing, but would also join the midfielders or attack from the right. He profited from the no-nonsense playing of Marcos Conigliaro, Juan Miguel Echecopar and Madero, and the tactical guidance provided by Bilardo. Right-back Eduardo Luján Manera was a very talented player, but suffered from repeated injuries and did not reach his full potential. Fullback Aguirre Suárez was noted for his often violent play, and so was Luis Medina. After the 1970 season, Carlos Bilardo retired from play and got involved in his family's furniture business. As the team's fortunes were declining and relegation seemed a possibility, he was called by management in mid-1971 to coach the team. Under his guidance, Estudiantes lost the 1975 Nacional title in the last day of play and made it to the 1976 Copa Libertadores. Carlos Bilardo era In the ensuing years, Bilardo alternated between coaching Estudiantes and Colombian teams. He was briefly the coach of the Colombia national team, but was called again by Estudiantes in 1982. Soon after, the team won the 1982 Metropolitano championship. Under his successor Eduardo Luján Manera, also a member of the Zubeldía's team, Estudiantes won the 1983 Nacional tournament as well. Both wins were at the expense of a star-studded Independiente. Those championship teams were anchored by a solid defense (Julián Camino on the right and Abel Ernesto Herrera on the left were also fearsome attackers, and José Luis Brown provided security as a sweeper), and also had three creative midfielders (José Daniel Ponce, Alejandro Sabella and Marcelo Trobbiani, with Miguel Ángel Russo to guard their backs) and two top-notch strikers (Hugo Gottardi and Guillermo Trama). Bilardo went on to coach the Argentina national football team, that won the 1986 FIFA World Cup. The captain of Estudiantes' 1982 champions, José Luis Brown, scored the opening goal
