"For us our objective has not changed. The win yesterday was very nice, very good for us, but our objective is to get through the first round," Benaglio told journalists at the team base camp in Vanderbijlpark, about 90km South of Johannesburg.
Switzerland stunned tournament favourites Spain with a 1-0 victory in their opening Group H game played in Durban on Wednesday.
"We don't think that much forward. The next game is against Chile. We have to do our best in that game and do not think of other things," Benaglio said.
"We knew that it would be very difficult even to get a point or to win against Spain. But I think we showed from the first minute that we believed in it. We had this belief otherwise we would not have done it."
"We beat Spain but we did not change the world ... it does not qualify us for the second round, so we have to stay humble," Nkufo said.
