If you are playing Defensive formation then You cant shut down opponents scoring Chances. They will even create more but it will be hard for them to score a Goal. Defensive formation works sometimes. but As opponents is still creating Chances he can Score a goal.Just like Some team in La Liga try to Defend vs Madrid & Barcelona but Match ends with more than 3 goals scored. If you want opponent to create less chances then just play possession football with short passing with crowded midfield. But he can counter if you lost the ball. There is no shutdown formation, actually. You can play defensive or Possession football to stop your opponent. But nothing is guaranteed
