"We can win another trophy if we treat approach the tournament with the respect it deserves. It's still a long road to the final though and it won't be easy."
Casillas moved on to discuss the 2014 World Cup and stated that Spain want to be successful in Brazil as well.
He added: "The qualification campaign for the 2014 World Cup hasn't started just yet, but we want to successful defend our title there [in Brazil] as well."
