Vicente del Bosque has given little importance to the friendly defeats of other teams regarded as favorites for the Euro 2012 title.
A much-changed Germany side suffered a surprise 5-3 defeat against Switzerland, while Netherlands lost 2-1 against Bulgaria, but Del Bosque is refusing to draw conclusions from the warm-up matches.
"I do not give any importance to Germany's defeat or to that of Netherlands," he told RTVE.
"These are just friendlies. What matters starts on June 8 [when the tournament begins]."
Just one day after announcing his final 23-man party for the Euros, Del Bosque confessed that he is thrilled with what he has found so far.
"We are mentally strong but we do not feel superior than anyone," he noted.
"We are delighted with the atmosphere in the group, with all those who are part of the squad, those who made the final group and those who did not.
"We hope it will continue like this because it is key for us to succeed."
The 61-year-old coach then explained the reason he left Barcelona's Thiago out of his squad for the tournament and hinted that continuity played a major role in his squad selection.
"Thiago had been to our liking in recent matches," he added. "But he suffered an injury which requires treatment and rest, and that is why we did not call him into the squad.
"If David Villa and Carles Puyol had not suffered injuries, we would have called up 21 of the 23 players who were at the World Cup."
