The 2021-22 campaign delivered ultimate heartbreak for Cagliari as Casteddu endured a tumultuous year, finishing a devastating 18th in Serie A, which resulted in relegation after a six-season stay in the top flight. Despite the constant managerial turmoil and three head coaches, the captain and talisman João Pedro led the line, whose 13 crucial goals proved a vital but ultimately insufficient contribution to the team's fight. The relegation, sealed on the final day, marked a painful chapter, yet the passionate spirit of the Rossoblu remained unbroken, defining a dark but unforgettable year in the club's modern history.
