The summer signing for City joins six other England-based players, including Chelsea quartet David Luiz, Oscar, Ramires and Willian and Tottenham midfielder Paulinho.
Scolari has so far only selected players based outside of Brazil, with the final spots to be filled nearer the beginning of next month.
"This friendly against South Africa is a different situation. It's no use me taking 23 players, 18 or 19 is the most I'll be taking," Scolari told a press conference.
"I'm always watching the players who are in action. If there are surprises, it will be a normal thing. I always call the players who are in a best position. I'll test some more players and then define the final list.
"The ones who are training, working, I'm watching. We could have a surprise up until the last call-up."
