Vicente del Bosque insisted nothing has changed for Spain after the two-time defending European champions crashed to a surprise 1-0 friendly defeat to Georgia.
After comfortable wins over Bosnia-Herzegovina and South Korea, Spain's Euro 2016 preparations were dealt a blow following Tuesday's warm-up defeat at the Coliseum Alfonso Perez.
Tornike Okriashvili's goal five minutes before half-time was enough to sink Spain, who had their 11-game unbeaten run ended.
But Del Bosque was not too downbeat post-match, as Spain prepare for Group D fixtures against Czech Republic, Turkey and Croatia in France.
"It was a disappointment. We have not played badly, but we have been unable to overcome an orderly defence," Del Bosque told reporters. "We appreciate what they did defensively.
"[But] we have an exciting challenge ahead and this result should not derail us.
"We face the European Championship with all the enthusiasm and without a trace of fear… Nothing changes."
Del Bosque, who opted to rest striker Alvaro Morata heading into Spain's opening Euro 2016 match against the Czechs on June 13, added: "The first half we played with many people behind the ball.
"We reacted in the second half and [Andres] Iniesta was more effective. We better understood the game but lacked finish [in front of goal]."
