South Africa U-23 coach Owen da Gama has described Nigeria and Brazil as the outstanding sides ahead of this summer's Olympic Games in Rio.
South Africa are in Group A in the men's football event alongside Brazil, Denmark and Iraq.
While the U-23 Eagles are drawn alongside Japan, Sweden and Colombia.
In a chat with FIFA.com, Da Gama stated that he is relishing the opening game against Brazil and hope South Africa go on to make an impact at the tournament.
“It might bring us luck. Who knows? I always prefer to start off against the big teams, though, and I think Brazil and Nigeria are the best two sides. After that, the only way is up," Da Gama said.
Da Gama went on to express hope that his team gets the backing of Brazilians in the course of the tournament.
“The people of Brazil have always been good to South Africa. We have a very good relationship,” he explained.
"We had (Carlos Alberto) Parreira in charge of our national team, which strengthened that sense of appreciation. We always get a very warm welcome there, and there’s no country in the world that has a better feeling for sport than Brazil.”
