RFEF president Angel Maria Villar insists Spain coach Vicente del Bosque's job is not on the line.
Spain suffered a shock defeat in their opening Group H match against Switzerland on Wednesday and the European Champions now face a battle to get through to the last 16.
Villar, the president of the Spanish football federation (RFEF), said: "I believe in this national team, a side that has obtained some excellent results.
"There is no issue with Del Bosque because he has a contract, he renewed in December and because there is total confidence in him.
"Whatever happens at the World Cup, Del Bosque will continue as coach. I'm very sure about that."
