part in the second edition of the European Cup. Qualification for this competition – contested between Europe's national champions – was achieved after Porto secured their fourth Primeira Divisão title in the previous season. Their debut was in a preliminary round tie against Spanish champions Atlético Bilbao. At their new home ground, the Estádio das Antas, Porto lost the first match 2–1 and were eliminated a week later in Bilbao, after a 3–2 defeat. Porto returned to this tournament two years later but fell at the same stage. After three seasons without qualifying for European competitions, Porto finished the 1961–62 league as runners-up and entered the non-UEFA-affiliated Inter-Cities Fairs Cup for the first time in 1962–63. They were knocked out in the first round by Dinamo Zagreb, who secured a draw in Yugoslavia after winning in Portugal. Porto returned to the Fairs Cup in the following season, but failed to advance past the first round. The Cup Winners' Cup was a UEFA competition open to domestic cup winners (or losing finalists, if the winners had already qualified for the European Cup). Porto qualified for this tournament for the first time in 1964–65, after losing the 1964 Portuguese Cup final against champions Benfica. Porto progressed from the first round of a European competition for the first time, after a 4–0 aggregate victory over French Cup winners Lyon, but fell in the next round to 1860 Munich. At the end of that season, Porto finished runners-up to Benfica in the league and qualified for the following season's Fairs Cup. The club's performance was similar to that of the previous campaign: a first-round elimination of a French team (Stade Français) followed by a second-round loss to a German team (Hannover 96), which included a 5–0 away defeat that was, at the time, Porto's heaviest in Europe. They took part in the Fairs Cup in the following two seasons, but could not progress beyond the first round. In the first case, Porto were eliminated by the flip of a coin, after extra-time was not enough to break the deadlock with Bordeaux. In 1968, the club won their third Portuguese Cup and qualified for the 1968–69 Cup Winners' Cup. As in previous years, they were unable to get past the second round, losing 4–1 on aggregate to Slovan Bratislava. Porto's last participation in the Fairs Cup, in 1969–70, also ended in the second round, with
