Nereo Rocco (20 May 1912, Trieste – 20 February 1979, Trieste) was an Italian football player and manager. He is famous for having been one of the most successful head coaches in Italy, and the first proponent of catenaccio in the country.
Rocco played as a wing, had a modest playing career, spent mainly with Triestina, Napoli and Padova. He played 287 Serie A matches within 11 seasons, scoring 69 goals. Rocco was also capped one time for the Italy national football team.
Rocco made his coaching debut for Triestina in 1947. He obtained a surprising second place in the Serie A, which is still the highest result ever reached by the team. He left Triestina a few years later because of disagreements with the club chairmanship. In 1951 he briefly coached Treviso, then returning to Triestina.
In 1953 Rocco signed as coach of Serie B team Padova, being able to avoid a relegation and obtaining promotion into Serie A the following season. The Serie A period of Rocco's Padova is still remembered as the team's most successful in their history, despite having a small team, they were able to score a third place during the 1957/58 season.
In 1961, Rocco was appointed as new AC Milan coach, starting one of the most successful periods for the rossoneri, winning the Italian league and the European Cup in 1963. After a good stint at Torino, where he obtained the best results since the disappearance of the Grande Torino, in 1967 Rocco returned to AC Milan, where he immediately won another scudetto and the Cup Winners' Cup.
He left AC Milan in 1973, after having won also another European Cup in 1969, an Intercontinental Cup, an Italian Cup and another Cup Winners' Cup. After one year in Fiorentina, Rocco decided to end his coaching career in 1974. In 1977 he was appointed by AC Milan as Technical Director and Assistant of coach Nils Liedholm. Rocco is Milan's longest-serving manager, managing the club for 459 matches (323 as head coach and 136 as technical director).
Rocco died in 1979, aged 66, in Trieste.
On 18 October 1992, a new stadium in Trieste, named after Rocco, was inaugurated.
Rocco, popularly known as El Paròn (Triestin for The Master), was popular also for his strong use of the Triestine dialect.
