Real suffer derby defeat to dent title defence
Getafe put a dent in derby rivals Real Madrid's defence of their Primera Liga crown with a 3-1 home victory.
Real now find themselves six points behind top-of-the-table Barcelona, who defeated Sevilla in Saturday's late kick-off.
Juan Angel Albin hit a brace and substitute Ikechukwu Uche also got his name on the score sheet as Real, who have won back-to-back league titles, could only respond through Javier Saviola.
Real boss Bernd Schuster has been under pressure for the duration of the season, but he received a vote of confidence from the club's board earlier in November.
However, the defeat to Getafe will only add to Schuster's critics and Getafe wasted little time in increasing the German manager's problems.
The home side took the lead in the third minute at Coliseum Alfonso Perez as Albin headed past Iker Casilias.
And two minutes after the half-time interval, Albin doubled his side's advantage as he fired in left-footed following a swift counter-attack.
Real hit back in the 55th minute as Saviola prodded in from close range, but that was to be as good as it got as Uche made sure of the points with eight minutes remaining.
