Spain defender Sergio Ramos is in confident mood heading into the World Cup and is keen to banish any thoughts of possible failure in South Africa.

Heading into major tournaments with high expectations is nothing new for the Spanish, but in the past they have often failed to live up to their lofty billing with a series of disappointing displays on the biggest stages.

"We shouldn't think about failure, we need to be optimistic. We must be positive and try to do a good job," said Ramos.
