Neymar, who suffered a fractured vertebrae in the World Cup quarter-final defeat of Colombia but made his comeback for Barcelona this week, is in the squad.
Only six of those who started the 7-1 mauling against Germany, David Luiz, Fernandinho, Hulk, Oscar, Luiz Gustavo and Maicon, feature.
Chelsea duo Ramires and Willian and back-up goalkeeper Jefferson are also maintained, but Marcelo, Dani Alves and Paulinho are among those dropped.
Captain Thiago Silva is missing after suffering a hamstring injury while playing for Paris Saint-Germain earlier this month.
