Turning the club into a title-challenging team took a while. Stade Dudelange and US Dudelange had been in Luxembourg's third tier (the National Division), whilst Alliance Dudelange was struggling to remain in the second league (the Division of Honour). The new club would take Alliance's place in the Division of Honour in the 1991–92 season.

In the 2012–13 UEFA Champions League, F91 Dudelange beat Tre Penne with an aggregate score of 11–0 and then met Austrian champion Red Bull Salzburg in the second round. They caused an upset by beating Salzburg 1–0 at home, and followed up that result by a 3–4 loss in Salzburg, qualifying them for the third qualification round for the first time on the away goal rule.

In the 2005–06 season, Dudelange completed the league and cup Double for the first time since the merger. They replicated this feat in the 2006–07 season, and won a fourth consecutive National Division title in 2007–08.

                                                                                       

It was formed in 1991 from the clubs Alliance Dudelange, Stade Dudelange, and US Dudelange. All three clubs had won the National Division or the Luxembourg Cup before, but each had fallen upon hard times, and the amalgamated club was expected to be more stable, in both a sporting and financial sense.

                                                                                                                                                                                 

F91 was promoted in its first season, and soon established itself as a competent top-flight team, not finishing outside the top half of the table until 1996–97. Towards the end of the 1990s, Dudelange gradually improved, and brought to an end Jeunesse Esch's era of dominance by storming to the 1999–00 league title by eleven points.
