Easy win
Choose a side to play on. Then during a game, press Start and choose "Select Sides". Move your controller under the opponent's side and resume the game. Then, score as many goals as desired (while under the opponent's side), then just switch back to your side again. This way you will have a big point lead, depending on how many goals you scored. This trick also works better when you switch back to your side near the end of the second half.
Easy goals
If you are defending or playing the ball around the midfield, get the ball from your opponents. Give the ball to a player whose shooting precision and power is over 60 and you may train them for better results (for example, Beckham, Figo, Ronaldo, Van Nistelrooy, etc.). Run to the half of your opponents. You may see a lot of space in front of you. Then, press Shoot. Just before the meter gets red, release it. The goalie will stand too far from his goal and the ball may go in. You have about a 50% chance that your player will score from way out.
Getting good players
Go to the options menu then to "Player Swaps". Swap all the good players desired onto the team you want to play as, then save that as a squad. Call it whatever desired. Then go to "New Season" and select "Current Squads" and play your team. This is useful for a third division team. This team now has all the good players.
Buying players
If you want to buy a player, bid for them about 1 or 2 million above the asking price. This ensures you of signing that player. Players that are worth buying include:
Thierry Henry
Ronaldinho
David Beckham
Ronaldo (either)
Tim Howard
Roberto Carlos
Alexandre Del Piero
David Bellion
Ruud Van Nistelrooy
Hernan Crespo
In the first year, it is almost impossible (unless you bid over 5 million above the asking price) to buy Thiery Henry, David Becham, Ronaldo, and Del Piero.
