Best. Game. Ever.
This game destroyed more joysticks than any other game in existence.
Scoring goals wasn't initially too crucial to my style of play, I preferred to fight non-stop for control of the score multipliers, and then gang up on on CM, CD and the goalie - get the ball, throw it to the other team and then beat the crap out of the guy that catches it until you get the ball back.
Once each of those three positions has been subbed off (money + points), spend the rest of your time scoring as many goals as possible (more money) and grabbing every little coin that appears (even more money). Spend your money on aggression, speed and power upgrades for your team, so you can hurt them quicker next time.
One of the best things about it was that although your initial squad was full of low skilled no-hopers in division 2, you couldn't improve the players you bought as much as the initial squad, so in order to compete in division 1 you needed to completely own division 2 without buying useless division 2 "star players" that would be passengers when promoted. You also need to make enough money over division 2 in order to get your players to a good enough level - crazy hard.
