The defender says that his side deserved more from the game in Bilbao...
The 24-year-old stopper also maintained that his side deserved more from the defeat to the Basque outfit having dominated proceedings for the majority of the 90 minutes.
"The five points is a significant gap and we have no margin for error," he told Marca.
"We deserved something more. We dominated the whole game, except for the first five minutes. We have tried everything to win, but the ball would not go in.
"They [Athletic Bilbao] have done a great job defensively and also as the minutes passed with the score in their favour they were gaining confidence, but we deserved a goal."
