Spain goalkeeper Iker Casillas has earmarked Arjen Robben as the main dangerman for Netherlands in their World Cup opener on Friday.
The two teams go head to head tomorrow night in a repeat of the 2010 World Cup final, which saw Andres Iniesta score the only goal of the game as Spain were crowned world champions.
Casillas believes that his side can defend their title with pride this year, but warned that former Real Madrid teammate Robben would pose a significant threat in their opening match.
"Robben is a great winger. I've known him since we were team-mates and I've come up against him several times since. He's great," Casillas told reporters.
"If we show the humility and enthusiasm we have over recent years then we'll be able to do well."
Casillas is the most-capped player at the World Cup finals, having turned out 154 times for his country.
