Switzerland defender Reto Ziegler believes his side can go far this summer because of their strong organisation.
The Swiss produced the result of the World Cup so far when they managed to beat European champions Spain 1-0 in Group H.
Ottmar Hitzfeld's men are now in an excellent position to qualify from the group, but they face another tough challenge when they take on Chile on Monday.
Sampdoria left-back Ziegler has praised Switzerland's organisation, and is now looking forward to taking on the South Americans.
"I think our strength is the organisation of the team. They had a lot of ball possession but we knew that (would happen) before the game," he said.
"I think the difference was in the organisation of Switzerland. We played well and we were more aggressive in the one against one.
"They wanted to play well against us but it was hard for them.
"Beating Spain is a good feeling. The first game in the tournament is always hard so we are all proud to have won this game against one of the best teams in the world.
"Now we have to concentrate on playing well against Chile because it's not good to win against Spain and then play a bad game the second time.
"We know we did something big and we are all proud for the country but now we have to concentrate against Chile this will be another hard game."
Switzerland could potentially qualify for the knockout rounds if they beat Chile and Spain fail to win against Honduras, but the likelihood is that the race to qualify from Group H will go right down to the wire.
