Portugal were very defensive against Spain, Spain had to do their best to break them down. You seem to have ignored the penalty Spain should have had against Paraguay immediately after their one was missed (the keeper brought down a Spanish player). And in the end, they won their games, a team who wins five out of six games (and if they win tomorrow within 120 minutes, six out of seven) deserves the World Cup. They started slowly but they've also shown why they're European Champions.
Plus I'd say a string of 1-0s show defensive solidity, which is usually needed to win the World Cup
