The club supported the "reorganisation" he demanded, however, and it used funds from the sale of three players to Liverpool to invest in the squad and make ground improvements at Oriel. McLaughlin's second league title followed in 1978–79, and they went on to defeat Waterford in the Cup final to complete the club's first League and Cup Double. The Double winning side's 1979–80 European Cup run the following season, where they narrowly missed out on qualifying for the quarter-finals (going down 3–2 on aggregate to Celtic), was the club's best European performance until 2016. They finished as runners-up in the league for the next two seasons, and achieved their only domestic cup double in 1980–81—winning both the League Cup and the FAI Cup. McLaughlin's third and final league title at the club arrived in 1981–82, after an early season 10-point gap to Bohemians was overhauled. A trophy-less 1982–83 season, which saw Dundalk slip to third place in the league table behind Louth rivals Drogheda United, signalled that the team was entering a transition period. But McLaughlin resigned in May 1983, saying he needed a change. After two seasons that ended in mid-table, former player Turlough O'Connor was appointed ahead of the League's split into two divisions in 1985–86. O'Connor quickly built a squad capable of challenging for honours and his sides consistently finished in the top four over the following eight seasons. They won the 1987 League Cup Final, and finished as runners-up in both the League and the FAI Cup to qualify for Europe for the first time in five years. The following season started with a visit from Cup Winners' Cup holders Ajax Amsterdam, and ended with the club's second League and Cup Double—with the title being won on the last day of the season, and the FAI Cup being won with victory over Derry City. O'Connor won his second League Cup in 1989–90, and another league title followed in 1990–91 in an end of season, winner takes all match in Turner's Cross against Cork City. But Dundalk spurned an opportunity to progress in the European Cup, when a 1–1 draw away to Honved was followed by a 0–2 home defeat. Attendances started to drop noticeably during 1992–93, as the new English Premier League, broadcast live on BSkyB, was growing in popularity. By the end of the season the board was facing financial issues that threatened the club's
