Spain boss Vicente Del Bosque says his position and that of some players could be in doubt after the defending champions' shock World Cup exit.
Defeat by Chile after a 5-1 thrashing by the Netherlands means the Euro 2012 winners cannot qualify from Group B.
"I think this team is good but we have to take a decision about what is good for Spanish football and that applies to myself as well," Del Bosque said.
He said his side were "sluggish and not brave enough" in the 2-0 loss to Chile.
Spain went into the tournament having triumphed at their last three major tournaments - the European Championships of 2008 and 2012, and the 2010 World Cup in South Africa.
But La Roja's campaign in Brazil got off to a humiliating start when the Dutch came from behind to rout them in their opening game and when they succumbed to two first-half goals by Eduardo Vargas and Charles Aranguiz at the Maracana on Wednesday, their reign came to an abrupt halt.
"In the first half we were really shy and sluggish and not brave enough so Chile were able to put the pressure on us," said Del Bosque, who has another two years left on his contract.
"In the second half we had more space and some chances but I am trying to find excuses - we played worse than Chile and Holland and so we have lost."
