Mexico's Oribe Peralta scored the only goal of a rain-lashed Group A game in Natal, securing a precious three points for Miguel Herrera's side. But the main talking point after the game was Colombian referee Wilmar Roldan who chalked off what looked like two valid Mexico goals in the first half. "The referee has taken two goals off us but we go away with three points and in top spirits," Mexico coach Miguel Herrera said.
