So the math for Copa do Brasil qualification is already locked in no matter who takes the trophy. here's how the spots actually shake out: there's one extra Pré-Libertadores spot heading straight to the Brasileirão. if Grêmio manages to stay up in Série A while finishing as champion or runner-up, they get a direct ticket to the next Libertadores group phase. but if Grêmio gets relegated despite winning or placing second in the Copa do Brasil, that entire Libertadores group phase spot flips over to the Brasileirão instead. basically Grêmio's relegation cooks the whole thing by opening up an additional direct Libertadores spot within the Campeonato Brasileiro. and tbh the nightmare scenario involves Grêmio facing Santos and Bahia, two teams desperate for that same extra direct spot in the Brasileirão.
