La Liga president Javier Tebas has admitted that the rest of the league season could be cancelled amid the global coronavirus outbreak.
As with much of Europe, all football in Spain has been suspended until April 4, with authorities yet to decide on how to conclude the remainder of the season.
Spain is the second worst-hit nation in Europe after Italy, with more than 6,300 recorded cases and 191 deaths.
And in what could be a precedent for major leagues including England, Tebas has indicated that abandoning the current season is a serious possibility given the nature of the pandemic.
Speaking to Spanish radio station Cadena Cope, he said: “I have been working all weekend via video conferences and telephone calls with European institutions and Spanish club presidents.
“We have a very important week ahead.
“What we are dealing with now will end the competition, and this will be a week of important decisions in Europe.
“I have been working with contacts in Italy and Germany to try and square up schedules, but this is a serious health matter.
“With 25% of the season still to go, we have will have to review our entire budget if the season ends now.”
Elsewhere, Valencia confirmed on Sunday that five of the club's players and staff have tested positive for coronavirus, including Argentinian defender Ezequiel Garay.
Garay was the first player in La Liga to confirm a positive test, and offered an update on social media.
"Clearly I've got off on the wrong foot in 2020," he wrote.
"I've tested positive for the coronavirus, I'm fine and now just listening to the health authorities, at the moment in isolation."
In England, it is unclear if the Premier League will abandon the current campaign, and clubs are set to meet on Thursday to discuss the next move.
Games across the country have also been suspended until 4 April, but Brighton's chief executive Paul Barber has admitted that it is difficult to imagine play resuming on that date.
Speaking to Football Focus, Barber said: "We've got several teams in self isolation, which makes it difficult to think about that date.
"Those players have not just got to self-isolate for 14 days, they've got to get themselves close to match fitness again, which could take another seven to 14 days.
"So we've got a number of complexities here, which go way beyond thinking of the finances."
