The 2020-21 campaign delivered back-to-back domestic glory for Flamengo as Mengão clinched the Série A title in a fiercely competitive season that ran into 2021. Despite the turbulence of three different head coaches, the team showed incredible resilience under Rogério Ceni to secure their second consecutive Brasileirão trophy. Spearheading the attack was the talismanic Gabriel Barbosa, whose 14 crucial league goals proved decisive. The season was also marked by cup success, with Flamengo adding the Supercopa do Brasil and Recopa Sudamericana to their collection, cementing this era as a defining chapter in the club's modern history.
