"We have to look at the positives. We played with a good rhythm, with intensity and we were very professional," said the coach, who also praised the efforts of Tahiti, who are 134 places below Spain in the FIFA world rankings.
"They have been an example of fair play and conducted themselves very well. They always went for goal every time they had an opportunity.
"Spain couldn't score more goals because the opponents did not let us. Football has not been damaged by this game, in some aspects it has been strengthened.
"The scoreline reflects the difference between professional and amateur football. Spain played seriously and with a lot of effort in search of the best scoreline possible, which is the best way of respecting your opponent."
Loud boos were audible inside the Maracana stadium throughout the game but the coach was certain the crowd reaction was part of the protests in Brazil that have been visible throughout the tournament and not at his players.
"I'm sure that the boos weren't aimed at us and were about issues beyond the football pitch," he said. "The fans showed affection for us during the game with Uruguay and have been kind to us every day we have been here."
Del Bosque fielded an entirely different starting 11 to the one that won the opening game with Uruguay and indicated he would rotate his side again for their final group match with Nigeria at the weekend.
He said: "The match allowed us to give minutes to everyone. Today the best players for this specific game played and on Sunday others will play."
