The weekends action will be rounded off by a meeting between Argentina and Mexico at Soccer City, the Argentines are the tournament favorites while Mexico have been impressive but could struggle against Diego Maradona’s star studded team who will be spear headed by FIFA World Footballer of the year Lionel Messi.
