FC Differdange 03

Two league titles in a row, in 2024 and 2025, arrived twenty-one years after the club's founding — and they came alongside a run in the Coupe du Luxembourg that ended in the final. The cup has been won seven times, most recently in 2025 and again in 2026, with earlier wins stretching back to 2010 and 2011. A Supercoupe still eludes the club: it lost the final to Progrès Niederkorn in 2024 and to FC Atert Bissen in 2026.

None of that was likely when FC Differdange 03 was formed in 2003 out of a merger between FA Red Boys Differdange, a club dating to 1907, and AS Differdange. The new side took over Red Boys' place in the top flight rather than starting from the bottom, and it has kept the name it was given at the merger ever since.

The clearest sign of what the club built came from between the posts. In 2025, the Brazilian goalkeeper Felipe went 1,561 minutes without conceding — sixteen matches clean, the fourth-longest such run in world football history. A different kind of statement came over a decade earlier, when Omar Er Rafik scored both goals in a 2-1 win over Utrecht in the 2013/14 Europa League, sending Differdange through at the Dutch club's expense.

The Reds play their home matches at the Stade Municipal de la Ville de Differdange, built in 2011-2012 on the site of the old Parc des Sports and holding 2,400 people. The fiercest test comes closer to home, against Progrès Niederkorn in the derby de Differdange.

Under Paolo Amodio, in his second spell in charge, the club won the 2023 cup.
