Capdevila says their counter attacking form can be "deadly".
He said: "This year we are enjoying our football very much. We will go to the Santiago Bernabeu to have fun and be confident that everything will go well. We will not repeat what happened last year when we lost.
"We have learned our lesson and go in with the idea of making a great game also of things going well. We will try to overshadow Real Madrid, because we have nothing to lose and everything to win.
"On the counter we can be deadly because we have very fast players. That will be our initial approach."
