The coach was in no mood to criticize his team, despite La Roja's shock elimination from the World Cup which they lifted in confident fashion four years ago
The reigning world and European champions became the first team to be dumped out of the competition on Wednesday - alongside fellow Group B opponent Australia - with a 2-0 defeat to Chile.
First-half goals from Eduardo Vargas and Charles Aranguiz left La Roja on the brink of elimination and a flurry of second half changes failed to save them. They'll face their final group game against Australia knowing they cannot reach the round of 16.

Del Bosque restrained from being critical of his team, which has conceded seven goals in two games, and instead tried to spin the defeat and World Cup exit into a positive light because his players had given their all.
"This is no time to assess if this exit will have consequences for me or the players," he told reporters. "You need necessary reflection and time to think - this is not the time to assess these situations.
"I think we have shown character despite our fairly straightforward elimination. We have gone forward, but have been unsuccessful in front of goal.
"For that we have no apology. We have all made a big effort. We had good intentions but we lacked something. We lacked a spark in the game. For the first time we have been very meek."
Spain will face Australia in both teams' final group game on Monday.
