Jonathan Joubert

The French-born Joubert started his career at the reserves of local side Metz before joining CS Grevenmacher for the 1999–2000 season. With them, he won the club's first domestic league and cup title in 2003, subsequently achieving the double. In 2004, he left Grevenmacher for Dudelange, where he ended up winning eleven league and five cup titles.

Joubert made his debut for Luxembourg in a June 2006 friendly match against Portugal and by October 2017 had earned 90 caps, scoring no goals. On 3 September 2017, Luxembourg held Joubert's native France to a 0–0 draw, with Joubert himself pulling off a string of saves to keep a clean sheet. Joubert's performance was later praised by French manager Didier Deschamps.

After retiring at the end of the 2022–23 season, Joubert was appointed goalkeeper coach at F91 Dudelange under manager Jamath Shoffner. In January 2024, Joubert was instead appointed as assistant coach, as the previous assistant, Claudio Lombardelli, had just been announced as the club's new manager. Ahead of the 2024–25 season, Joubert became assistant coach again, following the appointment of manager Marco Martino.
