Spain coach Vicente del Bosque admits their 5-1 thrashing by Holland has left him physically ill.
Switzerland upset the eventual winners in the opening World Cup game four years ago but the manner of this humbling could be harder to bounce back from.
"I feel sick, ill at ease, but with the courage a defeat must not sink us," he said.
"It is not a happy moment, but first of all I want to congratulate the Dutch team, who were superior to us. We have been overwhelmed in the second half.
"We are a team of good professionals and good lads, everyone hurts, so there were no accusatory glances and that's good for the team. There will be time to talk."
The veteran coach also declined to zero in on the performance of Iker Casillas, who was to blame for two of Holland's goals in a shaky performance.
Asked directly about his goalkeeper's display, Del Bosque said: "I insist that it is not the time to blame The defeats do not come through the performance of a player, but by the weakness of the team. We cannot blame anyone, least of all Iker ".
