who does Norway or Brazil play if they win?

Brazil and Norway are playing in a knockout match, so the winner advances to the quarterfinals rather than facing a group-stage opponent. For the quarterfinal matchup, the winner will play the winner of the other Round of 16 game in that bracket path ; one report frames that as the next opponent being determined by the bracket, not by Brazil or Norway directly.

In short: win here, and they move on to the quarterfinal bracket; the exact opponent depends on the other result in that side of the draw.

If you want the precise quarterfinal opponent, I can map the bracket path from the match page details.
