The 2021 campaign delivered a devastating and turbulent end to an era for Grêmio as Tricolor Gaúcho were dramatically relegated, finishing a crushing 17th in the Série A. Despite the prolific form of veteran striker Diego Souza, whose 10 league goals anchored an attack that also featured stars like Douglas Costa, the season was defined by constant managerial turmoil that saw four different coaches take the helm. Although the side achieved cup glory by winning both the Campeonato Gaúcho and the Recopa Gaúcha, their league fate was sealed on the final day, marking a heartbreaking conclusion and a painful, defining chapter in the club's history.
