The goalkeeper believes his team will create opportunities against the reigning world and European champions, but stressed the need to take them when they arrive
The two sides met back in June when La Roja strolled to a 2-0 victory in the quarter-finals of Euro 2012, but the Tottenham goalkeeper believes that his side can take all three points if they take their chances.
"It could be difficult, but we have to be together, and everyone has to put in a huge effort and hit them where it hurts. We will certainly have our chances, and we cannot let them pass," he told reporters.
The pair have had contrasting build-ups to Tuesday's encounter, with Spain strolling to a 4-0 win over Belarus, while Les Bleus fell to a shock defeat at home to Japan on Friday.
