SOMEWHERE in the world, a boy or a girl or a father or a mother is ripping open a pack of Panini World Cup stickers. They are hoping–no, praying –they will find stickers featuring stars like Leo Messi, Kaka (Ricardo Izecson dos Santos Leite) and Cristiano Ronaldo. If they don’t get the players they want, they will buy and rip open another pack, and then another–until they do.
