Baku, March 8, AZERTAC
Real Madrid were unable to increase their advantage at the top of La Liga after they were beaten by Athletic Bilbao at San Mames.
Athletic striker Aritz Aduriz, 30, put the hosts ahead with a header from Mikel Rico's cross.
Real dominated the game after half-time and Gareth Bale's audacious long-range effort struck the post.
But Athletic hung on to claim the victory which means Real have just a two-point lead over Barcelona.
The Catalan club will go top if they can take maximum points from Sunday's match against Rayo Vallecano at the Nou Camp.
