Lopetegui was roped in as Zinedine Zidane's successor at the Real Madrid in a three-year deal and, that he would take over the reins following the World Cup.
"We have decided to fire the national coach. What we have achieved in getting here is due in great part to him, and we must thank him and wish him luck," goal.com quoted Rubiales, as saying.
Rubiales further lashed out at Real Madrid for not speaking to Lopetegui without their consultation.
"Real Madrid look for the best coach, that is fine by me. I have no opinion about how Real Madrid act. But the federation have an obligation, to represent all Spaniards.If anybody wants to talk to one of our employees, they have to speak to us too, that is basic, as this is the team of all Spaniards. The national team is the most important we have, the WC is the biggest of all," he added
Though Rubiales did not reveal as to who will be in charge for Spain's opening game of the tournament, he confirmed that the announcement would be made anytime soon.
"We are going to touch as little as possible.We are working on it. When we know we will tell you," he said.
Lopetegui, who spent three years as a defender at Real Madrid, had last month penned a new contract with Spain to take him through to Euro 2020 in May.
