Casemiro struck his first World Cup goal with seven minutes remaining in the match to break Switzerland resistance and book Brazil's place in the Round of 16 here on Monday.
Brazil didn't alight on any rhythm in a stuffy opening half, their only attempts coming from Vinicius Junior, whose scruffy contact in front of goal allowed Yann Sommer to save, and Raphinha, who struck a hard hit effort into Sommer's midriff.
Richarlison, the two-goal hero against Serbia on Thursday, needed one shoe size bigger to connect with Vinicius Junior's cute outside-of-the-boot cross 11 minutes after half-time. And there was more frustration for Brazil when it came to light Richarlison was offside in the build up to Vinicius Junior slotting beyond Sommer after 65 minutes.
