The decision by Liam Tuohy to return to the club as captain, after four successful years at Newcastle United, effectively saw the completion of Thomas' side. The club won every domestic honour except the Top Four Competition in the 1963–64 season and were narrowly defeated by holders and eventual finalists, Valencia, in the Inter-Cities Fairs Cup. Thomas, however, quit the Hoops at the end of the season following a dispute with the Cunninghams (Owners) over team selection. Liam Tuohy took over as player-manager and led the club to a further five FAI Cups in succession, completing a series of six, including a 3–0 defeat of League of Ireland champions, Waterford in 1968, in front of 40,000 people at Dalymount Park. The summer of 1967 had been spent in the United States, participating in the foundation of the United Soccer Association, where Rovers represented Boston as Boston Rovers. The 1968–69 season saw Mick Leech score a total of 56 goals for the club, including two in the last FAI Cup final of the Six in a Row period, against Cork Celtic.

Their pre-match buildup was thrown into disarray when players and directors clashed over win bonuses. Hibs won the play-off 3–1. The next season, the Cunninghams, now under the control of sons Arthur and Des, sold the club to three brothers from Dublin; Paddy, Barton and Louis Kilcoyne. The Kilcoynes had witnessed decades of huge attendances at Irish football games and sought to take over the club primarily for business reasons. However, within the space of five years, the large crowds disappeared from Irish football stadia and combined with the demise of Drumcondra and Cork Hibs, the decline in fortunes of a number of top clubs and the lack of action by the FAI, the League of Ireland was plunged into a drastic decline. Faced with dwindling attendances, the Kilcoynes decided
