MASCHERANO'S CONCUSSION: Midfield general Javier Mascherano, and not Lionel Messi, looks increasingly like the man on whom Argentina's fate will depend. He was outstanding against the Dutch, snatching balls, creating and controlling the game and making life-saving tackles. Until he took a nasty knock on the head and became dazed. Mascherano will have four days to sufficiently recover from any ill-effects of the bang on his skull, and the hopes of his nation will rest upon him.
