Spain open their World Cup campaign in Brazil on Friday with a rematch against their defeated counterparts from the 2010 final, Netherlands.
Still ranked as the game's No. 1 side, Vicente del Bosque's world champions are expected to overcome Louis van Gaal's Dutch outfit at Arena Fonte Nova in Salvador.
