Cristiano Ronaldo scored a rare own goal to help struggling Granada complete their first win over Real Madrid in 41 years with a 1-0 home victory.
Jose Mourinho's side could hardly argue about the result having produced one of their worst performances away from home in recent memory with a lack of quality and urgency all too obvious in slipping to a fifth league defeat this season and a fourth on the road.
It was a wretched away performance only days after their spirited 1-1 draw with Barcelona in the first leg of the Copa Del Rey.
The winner came when Ronaldo tried to head clear Nolito's corner on 23 minutes, but ended up nodding the ball beyond Diego Lopez in the visiting goal.
Real huffed and puffed, but could not come up with an equaliser as Granada saw out the rest of the night fairly comfortably.
Granada are the first team to win a game without any shots on target in La Liga in the last 10 seasons.
It says enough that Ronaldo's haul of 21 goals in La Liga is more than Granada's total of 19, but it was a spirited performance from the men from Andalucia.
The mood of the night was best summed up when Karim Benzema missed an open goal in the closing moments after home goalkeeper Tono had halted a Jose Callejon shot.
Granada are out of the relegation zone while Real remain four points behind second-placed city neighbours Atletico Madrid having played one more game. They are also 15 behind champions-elect Barca.
