Being unpredictable is crucial to success in soccer. Once a defender or opponent can read what you're going to do, you're going to have massive amounts of trouble beating them. You must mix up your game so a defender never knows what you're going to do.
First time you get the ball pass quick, second time dribble at a defender, third time play a long ball, fourth time shoot, etc… Never allow obvious patterns to develop, go right, go left, go forward, go backwards.
Soccer is an athletic game of chess. You have to think ahead and outwit your opponent. Keep yourself unpredictable and your results on the pitch will be favorable.
