Looks like La Liga TV rights are being sold by two organisations, though not to say that Sky and BT could not buy them all.
1. Four clubs (Barcelona, Celta Vigo, Espanyol and Real Sociedad) recently agreed Spanish TV deals with Telefonica. International TV rights for their home matches will also be sold by
Telefonica.
2. The remaining 38 clubs from the top two divisions in Spain including Real Madrid will have their international rights sold by long-standing partner
Mediapro which ironically is based in Barcelona.
