Tite's team beat Switzerland to earn passage to the last 16 in Qatar
A goal inside the last 10 minutes from midfielder Casemiro was enough for Brazil to edge past Switzerland and seal a place in the World Cup knockout stages in Qatar with one group game to spare.
Casemiro struck with a sliced volley in the 83rd minute which appeared to take the slightest of deflections off defender Manuel Akanji before beating Yann Sommer in the Swiss goal.
After seeing off Serbia in their opening game, five-time World Cup winners Brazil are top of Group G on six points from two games.
The Swiss, who beat Cameroon in their opening game in Qatar, lie second in the group on three points, while Serbia and Cameroon are on a point apiece after sharing a thrilling 3-3 draw earlier on Monday.
While Tite's Brazil are safely through, the rest will fight it out for the remaining passage into the last 16 on Friday - when Cameroon will take on Brazil and Serbia meet Switzerland.
Brazil's win at Stadium 974 on Monday came without the star presence of Neymar, who injured an ankle against Serbia and seems set to be sidelined until the knockout stages.
Vinicius Jr thought he had given Brazil the lead in the second half after sliding the ball past Sommer, but the goal was ruled outside for an offside in the build-up following the intervention of VAR.
The Swiss, who had been involved in a minor traffic accident while making on their way to the stadium, appeared set to hold up Brazil for a second successive World Cup after their 1-1 draw in Russia four years ago, but found their resistance broken after a smart move involving Vinicius Jr and Rodrygo was volleyed in by Casemiro.
