Real Madrid's embarrassing exit from the Copa del Rey at the hands of Segunda B's Real Union has left under pressure manager Bernd Schuster searching for answers.
The Primera Liga champions, who have won the Copa 17 times, lost on away goals following a 6-6 aggregate draw and when asked why the defence was so leaky Schuster said: "I have no idea."
Madrid lost the first leg 3-2 in Irun and came from behind to establish a 4-2 lead at the Bernabeu, before Eneko Romo assured himself a place in the history books with a 90th-minute header to put the modest Basque side through instead.
It was the eighth goal Real have conceded in three home matches in all competitions over the last seven days and has lead to some players questioning the manager.
Madrid golden-boy Jose Maria Guti and defender Sergio Ramos have previously been critical of Schuster in the Spanish press and following Tuesday's defeat veteran defender Michel Salgado said the coach was struggling to find answers.
"If the coach doesn't know what's going in the defence, it's up to us to explain ourselves to him," Salgado said. "They have scored six against us in two games and we need to analyse this."
Club captain Raul notched a hat-trick at the Bernabeu, to take his club tally to 300 goals, and was bitterly disappointed to be the victim of a giant killing.
"It's a very painful defeat for the team and the fans and there is no justification," Raul said.
Despite criticism from the Madridistas, local media and some of his players Schuster insists he is not concerned about his position at the club.
"I am not worried, but I understand others are and they have doubts over the team and my work," the German coach said. He refused to explain who 'the others' were.
