Spain overpowered Ukraine 4-0 Wednesday in Group H of the World Cup - the biggest margin of victory so far at this year`s tournament. David Villa scored twice and Fernando Torres added a flamboyant fourth after a series of passes. As famous for its international flops as the finesse and flair of its game, Spain appears on the right track this time. It is on a 23-match unbeaten streak, all under coach Luis Aragones - a nice change for the nation whose checkered international soccer history has been one of perpetual disappointment.
