Tip: Your chances of winning a given contest are greatly enhanced if you maintain a good share of ball possession and take lots of shots on goal, two statistics that are prominently displayed throughout each match. So, shoot when you can and do a lot of seemingly unproductive back passing to keep those stats high.
Tip: Keeping the above tip in mind, remember that strengths build upon strengths and perseverance is the key. If you're playing well with lots of shots and possession but find yourself down on the scoreboard, keep at it--things should eventually go your way. A number of games can be won late in the second half when the defense finally succumbs to the pressure.
Tip: Late crosses from deep in the corner tend to find unmarked players in front of the net. Don't be afraid to go in almost to the dead ball line before passing for a one-touch shot.
Tip: If you're going to slide tackle, do it head-on or your chances of getting carded rise dramatically. Otherwise, go with a less vicious tackle and keep your men on the pitch.
Tip: The only thing better than winning a close AI game at pro or world-class level is winning a close multiplayer game at pro or world-class level. World Cup 98 supports network play, but it's just great head-to-head over a modem.
