was adopted, and on 11 April that year the ground now occupied by the Estádio do Bessa was inaugurated with a match against Leixões SC. In 1913–14, the team won the inaugural Porto Football Association. In the 1920s the club increased the number of sports practiced. The team boasted "the best defensive trio of the North": goalkeeper Casoto and defenders Lúzia and Óscar Vasques de Carvalho. In the following decade, the club lobbied for the legalisation of professionalism after being sanctioned, having been investigated after complaining that FC Porto had paid Boavista's Nova to join them. In 1933, the club adopted its black-and-white shirts, based on a French team that club president Artur Oliveira Valença had watched. League entry and golden 1970s (1934–1980) Boavista's first decades in league football saw the club bounce between the Primeira and the Segunda Divisão, winning the latter's title in 1937 and 1950. In 1966, they fell to the Terceira Divisão, and stayed there for two years. The team bounced back to the top flight by 1970 with two consecutive promotions, finished renovation of its stadium two years later and in 1974 hired manager José Maria Pedroto and president Valentim Loureiro. In their first year, Boavista achieved their best classification of fourth in the 1974-1975 championship, and won the Taça de Portugal for the first time after defeating Benfica 2–1 in the final. A year later, the club finished as runners-up to S.L. Benfica by two points, and defended their cup title by defeating Vitória de Guimarães 2–1 in the 1976 final at rival Porto's Estádio das Antas; Pedroto left for Porto at the end of the season. Experienced English manager Jimmy Hagan led the club to its third Taça de Portugal win in five years after defeating Sporting CP 1–0 in the replay of the 1979 final, after a 1–1 draw occurred the day prior. At the beginning of the following season, Porto and Boavista organised the first edition of the Portuguese Supercup, a season-opening match between the league and cup holders. The match was contested at the Estádio das Antas, and Boavista (with new manager Mário Lino) beat Pedroto's Porto 2–1 in a violent match where Boavista had two men sent off. From contenders to Champions and European forays (1980–2003) In 1997, Valentim Loureiro was succeeded as president by his son João, who at 34 was the youngest in the whole league. Also,
