Stringing together multiple passes will delight spectators and, ultimately, break down your opponent. No one player can single-handedly beat the opposition. Amateur mode is a good place to gain confidence in your scoring abilities. The defending in this mode is pretty slack, giving you an opportunity to practice different attacks and shots on goal. Defense Don't over-switch your defenders.
Timing is an important part of defensive gameplay.
Practice switching players until you perfect the timing of when to switch. Keep players in position to defend. If all of your players are attacking the goal, you're going to get burned when the opposition goes the other way. Always keep some defenders back, unless your defensive strategy consists of giving your goalkeeper an intense workout. A formation that effectively matches the team you are playing is essential.
