Dani Alves will become Brazil’s oldest World Cup captain against Cameroon on Friday.
The 39-year-old full-back, who now plays in Mexico for UNAM Pumas, will wear the armband as manager Tite prepares to make changes.
Brazil have already qualified for the last 16 with a top spot in group G guaranteed if they avoid defeat.
The former Barcelona defender has recovered from a knee injury to compete at his third World Cup.
Alves, who made his international debut in 2006, added:
Tite insisted he was not yet focused on the knockout stage, despite the anticipated changes.
“We have 26 great players and I do not have time to be focusing on the broader picture,” he said.
“We’ll make a few changes, we’ll include keys players. In two games, we used 19 players. We do not call them starting players or reserves, they are all players.”
Cameroon, who came back from two goals down in their previous game against Serbia to draw 3-3, must win and hope Switzerland fail to beat Serbia to go through.
Head coach Rigobert Song said:
Brazil have won both previous World Cup games between themselves and Cameroon - 3-0 in 1994 and 4-1 in 2014.
Brazil have won all seven of their World Cup matches against African sides, scoring 20 goals and conceding just twice.
A defeat or draw for Cameroon will see them eliminated from the group stage of the World Cup in their sixth successive appearance at the finals, last reaching the knockout rounds in 1990.
Brazil are yet to face a single shot on target at the 2022 World Cup, the first team to not face a shot on target in their first two games at a tournament since France in 1998.
Match kicks off at 9pm.
