Reading the article you don't think this is a little suspicious?
Los hechos analizados se remontan al 7 de mayo de 2001, cuando la Comunidad de Madrid, el Ayuntamiento de Madrid, y el Real Madrid firmaron un acuerdo para la recalificación de los terrenos de la Ciudad Deportiva madridista.
Como consecuencia del convenio, 30.000 metros cuadrados de terrenos considerados antes "equipamientos deportivos privados" y no urbanizables, pasaron a ser calificados genéricamente como terreno "terciario" o edificable. Posteriormente, parte de los derechos de edificabilidad de estos terrenos fueron vendidos a las empresas mencionadas
You obviously speak Spanish but for those who don't a quick recap says.
The community of Madrid, the city Council and Real Madrid came to an agreement in reclassifying the grounds where previously it was impossible to build habitable structures but was then made possible.
Anyone who has lived in Spain for a number of years knows these decisions are almost impossible to be reversed unless they have friends in very high places.
