The Bafana Bafana and the Selecao meet at the Soccer City stadium in Johannesburg (kick-off 5pm GMT) and Bayern Munich right-back Rafinha could make his first appearance for Brazil since 2008.
"I will do what I always do for my club," he told reporters in South Africa. "I've been called up because of what I do there.
"I must keep doing the same thing to remain in the national team. I must profit from this opportunity."
Fluminense striker Fred is happy to be back in the national team after missing six months of action with a muscle injury and he believes the Selecao will win the World Cup on home turf this year.
He said: "It's been a long time since my last game for the national team. I was injured but I will be rewarded for the work I did over the break.
"Nothing will stop me dreaming. I've been dedicated to my club for a long time and it's no different with Brazil.
"You have certain expectations in every game and you want the team to be more settled every time.
"I'm calm and aware of what I've been doing and how much I've prepared myself for this World Cup.
"It will be difficult for Brazil to lose the World Cup this year."
South Africa boss Gordon Igesund wants his team to spring a surprise on Brazil.
They shocked world champions Spain in November last year by beating them 1-0 at the same venue.
"We want to put up a good performance. We're playing a very good team - the five-time world champions," Igesund said.
"I've got a squad of players which will be our national team moving forward. We're looking to pick up where we left off.
"Everyone is fighting for places. We've got a good idea of who will be playing for Brazil.
"I've got to keep mentioning Spain. We played against the world champions and we dealt with them."
South Africa will have to cope without goalkeeper and captain Itumeleng Khune, who is missing due to sprained ankle, meaning defender Thabo Nthethe will take the armband.
The Mamelodi Sundowns centre-back said: "Every player is going to be excited about playing Brazil.
"I'm hoping I can do well. The players who are here know how Brazil play. I've done a bit of homework so I know what to expect."
