The world will be watching when Real Madrid faces Barcelona in Saturday night's El Clásico match. You're advised to savor the action.

As it stands, there will be no soccer matches in Spain next weekend after the Spanish players' union, the AFE, Friday called a strike over unpaid wages that will halt games in the country's top four leagues between April 16 and April 19.

The pay disputes apply mainly to soccer players playing in the lower tiers of Spain's professional soccer league, the LFP, but the strike was supported by a majority of players, according to the AFE.

In a statement Friday, the AFE confirmed that it had presented the Labor Ministry in Madrid with the official documents to call a general strike after negotiations with representatives from the LFP, Spain's sports council and the Spanish Football Federation failed to establish a "Grand Pact for Spanish Football" that would satisfy players' demands

"This strike will consist of the non-participation of players involved in official competition matches that could be played between clubs belonging to the Primera, Segunda A, Segunda B and Tercera divisions," the union said. The general strike won't affect "training sessions and technical activities," it added.
