Amad Diallo scored in the 90th minute to lift Ivory Coast to a 1-0 victory over Ecuador in its first World Cup appearance in a dozen years. The teams combined to hit the crossbar three times before the Manchester United winger - who entered as a substitute in the 56th minute - broke through with a left-footed shot from just inside the penalty area that beat diving goalkeeper Hernan Galindez. Wilfried Singo set up the goal with a strong run down the right side.
