The season will start on 18th August 2012 and run until 19th May 2013. Also in August will be the Super Copa between Madrid (Liga winners) and Barcelona (Copa del Rey winners).
So far the only club to be promoted from Segunda is Deportivo who return after a one year absence. The other two clubs to be promoted will be decided in the coming days, I will update the thread when these are known. The clubs relegated from Primera in 2011/12 were Villarreal, Sporting Gijon and Racing Santander.
Defending champions: Real Madrid
