Spain suffered a last gasp goal on Saturday, with Norway scoring a late equaliser to draw 1-1 and to leave coach Robert Moreno frustrated.
Saul Niguez's dipping second-half effort was cancelled out by Josh King's injury-time penalty to ruin Spain's 100% record in Group F.
After the game, Moreno discussed the bad feeling in the dressing room.
"When they equalise in the 93rd minute, you can't feel good," explained Moreno. "But that's part of football.
"We knew that they could be dangerous in that type of play.
"In the final minutes we were a little nervous and we risked too much, but that can happen."
Despite the setback, Moreno chose to reflect on the positives from the game.
"I liked the attitude of the team," he said.
"The players who played have done well.
"I think we generated chances to score the second, but I wish we could have defended those plays better."
