Vicente del Bosque says he already knows which 11 players will start Spain's World Cup clash with Chile on Wednesday.
The reigning world and European champions were stunned by Netherlands as they fell to a 5-1 defeat in their opening game on Friday.
Iker Casillas was at fault for several of the goals, while defender Sergio Ramos also came in for criticism after the game, which could see changes made.
That said, Del Bosque is convinced that his players are now over the hangover that ensued in the aftermath of that defeat and says they are very much alive in the competition.
"I was worried at first, but their heads are no longer down," he told reporters.
"Clearly the frustration will not go immediately, overnight. But we need people to know that we are aware of what is at stake here.
"Until their goal I thought we controlled the game. And then through [Arjen] Robben and [Robin]Van Persie they had a stream of optimism.
"I have profiled an eleven to face Chile, but I will not let them know in advance. If I do, that could alter the mood of the players before the game."
The 63-year-old was also quick to defend his players following the avalanche of criticism that has come their way and said they remain wonderful ambassadors for the country.
"There are many people who love us. This group has led us very far. When we were winning titles we were the saviours of Spain and now we're trampling the flag?
"We are not killed, we have a lot left to say."
