Hints:

Hint 1:

In FIFA, the program rewards goals and opportunities to the player who puts on the most pressure. Ball possession, time spent in the offensive zone, and a large number of shots on goal (no matter how weak they may be) all contribute to the ease with which program-controlled defenses break down and shots find the back of the net.

Hint 2:

Resist the urge to wildly switch players when under pressure in your own zone. Instead, maintain control of one player and press button 3 (the "gentle" tackle button) in rapid fashion. Because the program itself moves players to mark the ball carrier, any player who comes in contact with the ball will be ready to steal it.

Hint 3:

One of the best ways to move a ball around a tight defense is the button 1 lob pass, simply because nobody can steal it when it's in mid-air. Also, your intended recipient will almost always have more time, and experience less defensive pressure, when moving into position for a slow aerial ball than for a streaking ground ball.

Hint 4:

Once you're reasonably competent, set the referee strictness to Maximum. AI-controlled teams are usually quite aggressive, as are most new human players.

Hint 5:

If you're sprinting into the box with a defender nipping at your toes from behind, don't shoot. Instead, let him drag you down--he almost always will--and you'll reap the benefits of a penalty kick. Your chances of scoring from the spot are infinitely better than when you're hurtling in with defenders all around.
