Affectionately known as "Los Rojillos" or "The Reds", CA Osasuna is a club with deep-rooted history. Founded in 1920, the club started off in the third tier of the Spanish football league system and only made it to the La Liga in 1935. However, its first stint would be short as it was relegated to the Segunda División at the end of the season. After decades in the lower division, it would make its return to top flight football in 1980 and establish itself as one of the league's worthy members in the coming years. Although the club has always been a mid table table team, it has never been short of talent, with stars such as César Azpilicueta and Jaroslav Plašil having once worn its colors.
