Huesca won promotion back to La Liga on 17 July 2020, after a 3–0 win over Numancia and secured the league title on the last matchday. On 22 May 2021, despite winning two of their last five fixtures of the 2020–21 season, the club was relegated back to the second tier once more after drawing 0–0 on the last matchday against Valencia, the same team who had beaten them 6–2 to cause their relegation two years earlier. A month later, the club had its first Spanish international, goalkeeper Álvaro Fernández, who stepped in along with his under-21 teammates after the senior squad became unavailable due to a COVID-19 case.
