The 50-year-old's only previous coaching experience came at second division Oviedo, but he believes the players are ready to put the change behind them and focus on winning a second World Cup starting against European champions Portugal in Sochi.
Rubiales confirmed that the players attempted to save Lopetegui's job, but insisted that the RFEF were unable to accept the way Lopetegui handled the situation.
But if Spain gets eliminated after the group stage, many in the country will lay the blame firmly on Lopetegui, Rubiales and Madrid president Florentino Perez.
Lopetegui and Perez informed Rubiales just five minutes before Real's announcement, only three days before their first World Cup game, and the RFEF felt it was "unacceptable". There is a way of acting that must be fulfilled.
"We can not alter two years of hard work in the coming days". There is a lot to do.
Comparing the Spanish turbulence with England's camp so far, Butland added: "I don't think we'll ever be in that situation".
In 20 games, Lopetegui managed 14 victories and six draws, with 61 goals scored and 13 conceded - giving them the best record of any of the 24 teams in Russian Federation this summer over the last two years. [However], this has been done without knowledge of the RFEF.
Before news of Hierro's promotion, Rubiales said: "We are going to touch as little as possible".
When asked if he had rejected Madrid, Allegri told Sky Sport Italia: "Let's say I said yes to Juventus".
"It's a hard situation, but we are not the ones who determined the action that had to be taken", he said. The Spanish national team is the team of all the Spaniards.
Fernando Hierro, formerly a Real Madrid player himself, will transition from his role as the national team's sporting director to coach Spain during the World Cup. "We have been obliged to make this decision". I'm sure this will, over time, make us stronger. "I know the circumstances and Julen's work has been fantastic and I wish him all the best", he said.
"If it had been up to Julen it wouldn't have happened in this way and I wouldn't have found out five minutes beforehand".
All eyes will now be on Friday's game to see how the team react. In the RFEF we can not not fulfil our own values.
