Real Sociedad moved six points clear of the drop zone in La Liga after leaving the Santiago Bernabeu with a shock 2-0 win over Real Madrid on Sunday.
Willian scored an early penalty before Ruben Pardo added a second goal with seven minutes remaining to ensure the visitors earned a famous victory.
Real's case wasn't helped by Lucas Vazquez being sent off for a second bookable offence just after the hour mark. Defeat leaves pressure mounting on manager Santiago Solari following Thursday's 2-2 draw away to Villarreal.
What's Next?
Real are in Copa del Rey action at home to Leganes in the last 16 on Wednesday, before returning to the league for a tricky trip to Real Betis next Sunday.
