Several Spanish clubs have complained over non-payment of fees for television broadcasts of matches.
Six clubs in the first division and most of those in the second division have not been paid this month by AVS, a subsidiary of media group Sogecable, which holds the broadcasting rights, according to La Gaceta de los Negocios.
AVS said the non-payments were due to financial difficulties, the paper reported.
AVS holds the broadcast rights to matches for 12 first division clubs, including those of league leaders Real Madrid and arch-rivals Barcelona.
Sogecable, which operates Canal Plus in Spain, and the Mediapro group have been locked in a battle to control television broadcast rights, which has at times led to certain games not being screened.
In July 2006, the two groups agreed that AVS could have broadcast rights. But Mediapro then negotiated with the clubs to hold those rights from 2009, excluding Sogecable from the market.
Since then each side has accused the other of failing to respect their commitments.
