Spain dramatically sacked coach Julen Lopetegui on Wednesday and appointed federation sporting director Fernando Hierro -- just two days before the team's opening game at the World Cup.

In a surprise announcement on Tuesday, Real Madrid appointed Lopetegui as Zinedine Zidane's successor to take over after the tournament in Russia, sparking outrage among the federation and Spanish fans at the timing of the announcement.

At a severely delayed press conference at Spain's World Cup base in Krasnodar, Spanish football federation (RFEF) chief Luis Rubiales expressed dismay at the timing of events that threaten to derail Spain's World Cup chances.

"The national team is the team for all Spaniards and there are some decisions we feel obliged to take to protect some values," said Rubiales. "Negotiating is legitimate but it took place without the RFEF being informed until five minutes before a press statement was released. There has to be a message for all workers in the federation that there is a right way to do things."

Later Wednesday, Spain named Hierro as the coach for the tournament in Russia.

"Fernando Hierro will assume coaching responsibilities at the World Cup in Russia," the Spanish football federation announced.

The 50-year-old Hierro's only real coaching experience came when he was in charge of second division Spanish outfit Oviedo for one season.

Lopetegui had signed a contract extension until 2020 just last month and never tasted defeat in his 20 games in charge as Spain boss. Spain are due to face European champions Portugal in Sochi on Friday before taking on Iran and Morocco in Group B.

There were fears Lopetegui's appointment by the European champions could open up old divisions between the Real Madrid and Barcelona factions in the Spain squad.

However, according to reports in the Spanish media, the players tried to intervene at the last minute to prevent Rubiales sacking Lopetegui.

"I have spoken with the players and what I can guarantee is that the players will do everything in their power, along with the new technical team to take the team as far as possible," said Rubiales.

La Roja were among the favourites to lift the trophy this summer but the astonishing developments of the past two days could have a devastating effect on their chances.
