UNA Strassen

Early years (1922 - 1999)

The club was founded in 1922 as Union Athlétique Strassen (UNA Strassen). The following year, UNA Strassen became affiliated with the Luxembourg Football Federation.

Playing a modest role in the lower divisions of Luxembourgish football, UNA Strassen would see a halt in their journey due to the occupation of Luxembourg (1940–45) during World War II. After the liberation of Luxembourg in September 1945, the Luxembourg Football Federation declared all results of competitions under the Nazi Regime void.

The 1998–99 2. Division season was the take-off season for UNA Strassen. They topped Serie 2 of the Division (the second of four groups), and so earning themselves promotion from the 4th tier to the 3rd tier.

Post-2000 successes (2000 - )

The wait for another promotion was at last ended just over 10 years after their pre-millennium success. In the 2010–11 1. Division, UNA Strassen secured top spot of Serie 2 (the second of two groups), and in turn gaining promotion once more, this time to the Division of Honour (2nd tier).

Their time in the 2nd Division was short-lived, with the side taking only 4 years to reach the top flight from there, gaining promotion to the 2015–16 National Division after finishing third in the 2014-15 Division of Honour and winning their playoff match.

UNA Strassen recorded five top-10 finishes in the Luxembourg National Division over a five-season period. During the 2023–24 season. They had also been performing in domestic competition, going out in the Semi-Final of the 2023–24 Luxembourg Cup to FC Swift Hesperange 2-0. Qualification for European competition (as discussed below) that same season really established them as one of a handful of prominent sides in the Luxembourgish footballing world.

After the conclusion of the 2023–24 Luxembourg National Division, UNA Strassen qualified for European Football for their first time, qualifying for the 2024–25 Conference League despite finishing 6th (outside of the qualifying spots which are 1st-3rd + the Luxembourg Cup winners). This was due to Swift Hesperange and Jeunesse Esch (two other clubs who play in the National Division) being denied their UEFA Pro Licenses.

The end of the 2024–25 BGL Ligue, saw UNA Strassen achieve their highest ever position in the Luxembourgish top-flight, finishing in 2nd place. This meant that the side qualified for European football for the second time ever, the first time being the previous season. This season however, they qualified for the 2025–26 Conference League 2nd Qualifying Round., instead of the 1st Qualifying Round the previous season. Not only this but one of their forwards, Matheus (Nogueira de Souza), was top scorer in the league.

Before the 2026–27 season, the club announced Jérémy Deichelbohrer as their new first team manager.
