The 2020-21 campaign delivered a season of heartbreaking struggle and ultimate disappointment for SD Huesca as Oscenses finished 18th in La Liga, resulting in immediate relegation back to the Segunda División. It was only the club's second season ever in the top flight, and despite a mid-season managerial change from Míchel to Pacheta, the team could not overcome a difficult start that included a 12-game winless run. Leading the valiant charge was the prolific on-loan forward Rafa Mir, whose crucial 13 league goals were a shining light in a campaign built on resilience and a desperate final-day battle for survival. Despite the outcome, this turbulent year marked a memorable, if painful, chapter in the club's modern history of brief top-flight appearances.
