Flamengo beat Fluminense 1–0 at the Maracanã on Sunday (11) in Matchday 30 of the 2026 Brasileirão.

With important Conmebol Libertadores fixtures during the week, both rivals opted to rotate their squads heavily.

Fluminense, for example, made seven changes to their starting lineup.

Flamengo, with a deeper squad, made just three changes from their last match (a 2–2 draw with Santos).

Against this backdrop, Flamengo dominated the Rio derby, pressing their rivals as they tried to play out from the back and allowing them to create very little.

The first half, however, remained goalless. The most notable incident before the break was Pulgar's studs-up challenge on Castillo's knee, but the referee only showed the Flamengo midfielder a yellow card.

After the break, though, Flamengo needed 20 minutes to open the scoring.

Lucas Paquetá crossed from the right, and Carrascal struck a fine first-time finish to beat goalkeeper Fábio.
