Spain striker David Villa remains confident his team will progress to the last 16 despite yesterday's shock opening defeat to Switzerland in World Cup Group H.
Gelson Fernandes' goal seven minutes into the second half condemned Spain to a first loss to the Swiss in their history, causing the first major upset of South Africa 2010.
"We are annoyed by the result," said Barcelona new boy Villa. "We dominated possession and we were the better team.
"But this is football, and not always the best team wins."
The result leaves Spain needing victories against Chile and Honduras to be assured of progressing to the knockout phase, but Villa is staying upbeat.
"We are aware that the tournament has only just begun," the 28-year-old continued.
"We would have preferred to have had everything going in our favour but this is a World Cup and nothing is as easy as it seems.
"Nevertheless, we are convinced that we will go through to the next round."
Villa believes yesterday's game was almost identical to the game Spain lost 2-0 to the United States in the Confederations Cup last summer.
"It was a copycat from that semi-finals of the Confederations Cup," he said. "The only difference is that we are not going home."
The former Valencia frontman does not expect a big change in the European champions' tactics for the remaining two group games.
"With this style of play, we have only lost two games," he said. "We need to continue to play the same.
"We are not going to change our style just because of this defeat.
"It has been down to our play that we have achieved success in the past."
Switzerland coach Ottmar Hitzfeld hopes his team's historic triumph will mark the beginning of something great.
"We have much more to come," he said. "We have to build on this performance in our next two games if we want to progress to the last 16."
Hitzfeld admitted the Swiss never expected to beat Spain, and wants his side to show the same spirit and determination in their remaining group games.
"The win against Spain was exactly what we needed," he said. "It was three unexpected points but we gladly take them.
"However, Chile is just as difficult as Spain is and we must play with the same determination.
"The good thing is that my team will go into that game with plenty of confidence."
The Swiss will also be bolstered by the return of captain Alexander Frei, who missed yesterday's game due to an ankle injury.
"We expect to have Frei with us in training on Friday," said Hitzfeld.
Spain take on Honduras on Monday in Johannesburg while Switzerland face Chile on the same day in Port Elizabeth.
