Javier Tebas, vice-president of the Liga de Futbol Profesional (LFP), believes that there is match-fixing in La Liga, and fears that a similar scandal to the Scommessopoli controversy that has rocked Italian football could be on the cards.
Tebas has little doubt that the results of certain games have been fixed, but has admitted that he has no evidence to back his claims.
"Games are being sold in La Liga and the cheaters must be exposed," the LFP vice-president told Onda Cero in an interview.
"Unfortunately, I cannot prove it, but games are being fixed in Spain. I cannot rule out a similar scandal to the ones in Italy."
Tebas also had his say on the low attendance figures in Spain, and blamed the country's financial crisis for the lack of crowds.
"The low attendances do not have anything to do with the schedule," he said.
"It's the logical result of the economic crisis. And numbers have dropped by only 3.5 per cent."
