The Spanish Football League (LFP) is to appeal against a FIFA decision preventing it from extending the Primera Liga season by another week.
“We are taking this decision in order to safeguard the purity of the competition,” a spokesman told a news conference on Wednesday.
“Tomorrow we will present an appeal against the FIFA ruling in a Zurich court.”
The Spanish Football Federation (RFEF) had proposed extending the season until May 20 in order to accommodate the rescheduled match between Sevilla and Barcelona which was postponed on April 23 because of a water-logged pitch.
FIFA rejected the proposal to play all 10 final league games on that date because it was later than the May 15 deadline agreed to allow national team squads time to prepare for the World Cup.
They did, however, allow the Sevilla-Barcelona match to be played a week after the end of the season on May 20, but without any players involved in the World Cup.
Spanish clubs who run the LFP complain that the decision will give Sevilla an unfair advantage because Barca will play without most of their first-team squad.
