The last three matches between the sides have been draws, Isco was the hero (for a given value of 'hero') when they last met in September, snatching a point for Los Blancos after Iker Muniain put Athletic ahead.
Los Leones haven't beaten Real since March 2015 though, and are without a win at the Bernabeu in 14 years. There have been nine draws between the teams, Madrid have won 34 and Bilbao have triumphed on 12 occasions.

Who will win this game?
Madrid are capable of beating anyone on their day, but those days have been few and far between this season. Athletic's recent consistency does hint that, despite their poor record at the Bernabeu in the last decade, they could grab something on Sunday.

Predicted scoreline: Realmadrid 2-1 Athletic club
