In the 1960s, Miguel Ignomiriello coached the Estudiantes under-19 team known as "La Tercera que Mata" ("The Killer Juveniles"), which would evolve, with a few acquisitions, into the team coached by Osvaldo Zubeldía that won the 1967 "Metropolitano" championship. With this title, Estudiantes became the first club outside the "big five" (Boca Juniors, River Plate, Racing Club, Independiente and San Lorenzo) to obtain a professional title. This opened the floodgates, and soon other "small" clubs would do likewise (Vélez Sársfield in 1968, Chacarita Juniors one year later, and soon other teams joined as well).
