No quite sure what you're on rambling on about now. I haven't said we'll lose if Bravo plays. The point being made is that playing Ederson over Bravo increases our chances of winning. And, to repeat, taking into consideration Bravo's poor form, likely departure in the summer, our general weakness at the back, the League gone, and Ederson not requiring a break, the best bet here is to play Ederson in order to increase the chance of advancing to the next round.
Why does Bravo deserve automatic selection just because it's a cup game? Nobody deserves that. Form has to play a factor, and Bravo has stunk this season. I doubt there would be a problem with him lining up otherwise.
