After Castilla's win against Guadalaraja, Arbeloa was asked about the rumours and replied emphatically: "No!
"I'm the Castilla coach and I'm focused on that. On my players, on the matches ahead, on training, and there's nothing else on my mind."
He also said, . "Anyone who thinks Real Madrid is finished is very wrong. Xabi is an outstanding coach."
