There are plans to implement VAR in La Liga from the beginning of next season, according to acting Royal Spanish Football Federation (RFEF) president Juan Luis Larrea.
La Liga president Javier Tebas has claimed the technology is too expensive but Larrea says the RFEF are prepared to embrace a change.
"The intention is to have VAR from the first matchday in La Liga next year," he told Cadena Ser.
"There is technology coming into football and you have to accept it."
Larrea, who has held the top job at the RFEF since Angel Maria Villar was arrested in July as part of an anti-corruption investigation, also suggested changes could be made to the Copa del Rey format.
Every stage of the tournament from the round of 32 onwards is played over two legs, prompting critics to decry the number of matches and the reduced possibility of an upset.
Espanyol boss Quique Sanchez Flores claimed recently that "everyone loses" under the current format but Larrea says he will listen to clubs if change is widely desired.
"There is something about the current format. I like it," he said. "I believe it is even good to play over two legs.
"It's what they wanted. We will change when they want to."
