The 1998-99 campaign was a deeply turbulent season of managerial upheaval for Atlético Madrid as Los Colchoneros struggled to find consistency, finishing a disappointing 13th in La Liga. Despite the domestic struggles, the team, featuring the emerging talent of young striker José Mari whose 9 goals were crucial, delivered dramatic cup runs, reaching the Copa del Rey final and the UEFA Cup semi-finals for the second year running. It was a chaotic year marked by the return of Radomir Antić, but it tragically signaled the start of a difficult period for the club.. The 1999-00 campaign delivered a devastating end to an era for Atlético Madrid as Los Colchoneros crashed to a crushing 19th-place finish and suffered relegation to the Segunda División. Leading the charge was the phenomenal striker Jimmy Floyd Hasselbaink, whose 24 goals were a spectacular individual performance but proved tragically insufficient in a season of unprecedented turmoil and multiple managerial changes, despite reaching the Copa del Rey Final. This monumental failure marked a necessary turning point for the club, one that ultimately paved the way for the emergence of the young Fernando Torres.
