Four points will be enough for China to reach the second phase of the World Cup, according to their coach Bora Milutinovic.
The Yugoslav, who is suffering from a severe cold, believes that his side can make it through a difficult group for the World Cup newcomers.
Milutinovic, who has also guided Mexico, Costa Rica, the United States and Nigeria, to the World Cup finals said: "We need maybe four points to go through. I don't like to make calculations.
"We need to respect the opponent but we have to play our own game and, well, sometimes you win and sometimes you lose."
Milutinovic has also defended the team's decision to post a letter on the internet last week pleading with Chinese fans not to expect too much from his squad.
More than 40,000 Chinese fans are expected to travel to Japan and Korea to watch their country's first outing in the World Cup finals.
Milutinovic said: "Expectations are already high. Everybody is thinking about Brazil without respect.
"We need to respect them, but this does not mean we are going to lose."
He added: "The players have done a great job but now this is the question: when you come on to the pitch, what will your attitude be? Attitude is everything".
"We do not read the newspapers and we do not watch television. I try to get my players to feel that they're not in the World Cup."
Meanwhile, China have at last been given some good news on the injury front.
Key defender Fan Zhiyi looks likely to have recovered from a foot injury in time for the Costa Rica game.
Milutinovic is yet to make a final decision on the Dundee defender and he trained on his own on Thursday with a heavy bandage on his left foot.
Midfielder Yu Genwri, who has been having treatment for knee ligament damage since the end of the Chinese league season, was impressive in attack for the reserve team in training.
