Real Madrid's stellar talents were humbled 4-1 by mid-table Sevilla last night as the superstars' defence was torn apart by the 14th-placed team.
Real, missing key defensive players, found themselves 3-0 down after only 14 minutes and went in at the break 4-0 behind.
Real coach Carlos Queiroz was forced into a defensive reshuffle, with Michel Salgado suspended and the talismanic Roberto Carlos out injured.
The decision to replace the regular fullbacks with Francisco Pavon and Raul Bravo and bring in youngster Ruben to partner Ivan Helguera in the centre looked to be a risky one and Sevilla were soon in total charge.
Ruben headed a cross into the back of Helguera to hand Sevilla their opening goal after four minutes, as the ball rebounded back past Iker Casillas and in.
Three minutes later, Sevilla were two up, with Jose Antonio Reyes sending in a weighted pass for Dario Silva to convert.
Daniel Alves added the third, lifting the ball over Casillas after an exchange of passes with Antonito.
Queiroz reacted by replacing Ruben with Santiago Solari but Real's fortunes scarcely improved and Francisco Casquero made it 4-0 after Reyes had stolen the ball from Pavon to create the opening.
Real sharpened up their act in the second half but Ronaldo's drilled finish was all they had to show for their efforts as Sevilla held on for victory.
