INNSBRUCK, Austria (Reuters) - Spain goalkeeper Iker Casillas complained the official World Cup ball was better suited to the beach than to the finals in South Africa after his side's 3-2 warm up win against Saudi Arabia.

"It's a bit like a beachball," the Spanish captain was quoted as telling the Spanish media on Sunday before going on to describe the unpredictable movement of the ball.

"Now it isn't only the goalkeepers (complaining) it is the outfield players as well. It's sad that a competition as important as a World Cup has an element as vital as the ball with such abysmal characteristics."

Midfield playmaker Xavi said: "It's a question of getting used to it but in truth it does move around a lot."

Casillas earned his 103rd cap in Innsbruck on Saturday, overtaking Real Madrid team mate Raul to become the second most-capped player in the country, behind another keeper Andoni Zubizarreta with 126.

They have a chance to sharpen up in their next friendly against South Korea, also in Austria, on Thursday.

Spain will face Switzerland, Chile and Honduras in the group stages of the World Cup which kicks off on June 11.
