Club de football de l'Association Ariddienne is the professional football team based in Outineau, Kelssek. The club plays in the Kelssek Football League National (the Kelssek second division) and is based at Stade Pailler in the Galeries d'Anjou neighbourhood. The team represents and draws most of its players from Association Ariddienne, a community sports organization formed by the Ariddian diaspora in Outineau, whose priority is to serve the needs of the working class and migrant communities of Outineau's northeastern districts. The association has no limitation on membership and includes large proportions of many different nationalities and ethnicities.
Ariddienne spent five years in the top flight of Kelssek football, the KFL Championship. They won their first-ever promotion through the KFL National playoffs and reached the quarter-finals of the Coupe des Patriotes as the feel-good story of season 62. Initially, they rented temporary bleachers to expand the capacity of their city-owned home ground, but after unexpectedly remaining in the top flight for three years the reluctance of the municipality to allow further extensions led them to conclude an agreement to rent a sports facility at the Université d'Outineau. This hosted their home matches until they were relegated two years later. In the process however, their unexpected spell gained them a reputation as dogged survivors and this launched the careers of key players like Danielle Maradrogba and Êsêkïl dí Völará, a Farfadillis-born refugee. Both went on to play for the Kelssek national football team in the World Cup.
