Vicente del Bosque will make changes to his starting XI for their match against Chile following their 5-1 defeat by the Netherlands.
"It was a hard defeat," he told reporters on Saturday, "but step by step we are accepting that it isn't a crucial loss.
"We hope to move on for the next match with all respect to Chile, who also want to qualify for the next stage.
"Of course there will be some changes, but I don't want to make any rash decisions, I have until Wednesday to decide who will be dropped. There's no need to single anybody out, we have 23 players available and we'll find the best possible solution."
