Spain sacked head coach Julen Lopetegui after he was named the new Real Madrid boss - two days before their opening World Cup match against Portugal.
Real Madrid announced on Tuesday that Lopetegui would replace Zinedine Zidane at the Bernabeu on a three-year-deal.
The Spanish football federation (RFEF) said it had dismissed the 51-year-old because the negotiation occurred "without any information to the RFEF".
The World Cup in Russia starts on Thursday.
