It's football versus the government in Spain as the federation that represents La Liga is threatening to call off the games currently scheduled for the weekend of April 2nd to protest a law that the league claims is costing the teams money. The law in question mandates that one match per weekend be shown on free television, which sounds wonderful for the fans but not so good for the teams, whose revenue is tied in large part to TV income.
The league has been in talks with the government over scrapping the rule, but they've apparently gotten nowhere and so threats are being made to cancel an entire weekend of games if talks don't progress swiftly. The match day in question includes Barcelona's visit to Villarreal and Real Madrid hosting Sporting Gijon. While it seems unlikely that such a strike will actually happen, the threat is very real. A statement from the league read:
[T]he LFP stands by the decision... to postpone the matchday which corresponds to April 3, until there are concrete developments in the dialogue with the administration.
I'm not entirely sure that the government would want to be responsible for the cancellation of a whole round of fixtures, but then again they're the ones fighting for more free football. Time will tell who caves first.
