Brazil were heavily booed as they failed to break down a dogged South African defence and ended the game in a stalemate. The South Americans are favourites to win the tournament, which has the likes of Neymar and new Manchester City signing Gabriel Jesus in the squad, with the Barcelona man taking leave from Brazil's Copa America exploits to feature in the tournament.
Jesus had the best chance to take the lead in the second half but struck the post with the goal at his mercy. They will be desperate to right the wrongs from their last game and make their way into the next round and go forward in their quest to end their medal drought in the tournament.
Meanwhile, Iraq were also held to a 0-0 draw by Denmark and both teams need a win to extend their participation in the tournament. The Asian nation qualified for Rio by finishing third in the AFC Cup, beating hosts Qatar on the way. This is only the second time they have qualified for the group stages of the Olympics, with their last involvement dating back to 2004 in Athens.
Possible XI: Weverton; Zeca, Marquinhos, Caio, Santos; Anderson, Maia, Augusto; Gabriel, Jesus, Neymar
Possible XI: Hameed; Tariq, Ibrahim Khalaf, Nadhim, Ismail, Adnan; Kareem, Attwan, Abdul Ameer, Husni; Ahmad
