The 1999-00 campaign delivered a devastating end to an era for Real Betis, as Los Verdiblancos spectacularly burnt out, finishing a crushing 18th in La Liga, which resulted in relegation after a six-season stay in the top flight. Leading the fight was club icon Alfonso Pérez, whose 10 goals proved vital in a turbulent season that saw the club cycle through three different managers. Despite the instability, the team did achieve a memorable 2-1 home victory over Barcelona. It was a dark year defined by inconsistency and remains a painful but defining chapter in the club's modern history.
