Maria Tena, commissioner general of the Spain Pavilion, and Walter van Weelden, commissioner general of the Netherlands Pavilion, exchange national soccer team jerseys yesterday afternoon at the Shanghai World Expo to celebrate both countries' entry into the World Cup final. Meanwhile, Paul, the oracle octopus who correctly predicted the outcome of every Cup match played by Germany, is branching out and will weigh in on the Spain- Netherlands final. He will make his choice this morning on the runnerup Germany-Uruguay match, then pick the winner of Sunday's final in Johannesburg.
