Magnetic ball:
In any exhibition match, press Start, then press Up, X, Up, X. The game will quit your match. When you start a new match, in the general settings there will be a new option named "Magnetic Ball". When activated, you cannot lose possession.

Hint: Swapping players to different teams:
Go to edit mode. Go to registration player, then select the team that has the player first. Next, click on the player that you want to move. Another half screen will appear with the team names on it. Select the team, and when you play a match with them he will be there.

Hint: Maradonna move:
Rotate the Left Analog-stick 360 degrees clockwise to do the Maradonna.

Hint: Trevor Brooking's voice:
Press any button at the title screen. Leave the game at the main menu for a few minutes until it returns to the introduction sequence. Watch or skip the introduction to go back to the main title screen again. Trevor Brooking should now say "Pro Evolution Soccer 4" instead of Peter Brackly.

Hint: Easy money:
When you are doing a cup, remove your memory card and do the cup. When you have won the cup, you will get a lot of money. Then, go to the shop and buy anything. When you have selected what you want to buy, insert your memory card again and save what you have bought. The cup that you won will not be saved. Restart the game and the cup you have just won will be gone, but the item that you bought will still be there. Do the cup again and to get a lot of money again.

Hint: Easy shop points:
Go into International League mode and choose to play only three teams in one half of a season. Make sure you end up at the top of your league. After your three games, you will get 1,500 PES Shop Points for winning the league. You will also get 50 points a game (150 total) to that as well.

Hint: Easy goals:
When the ball has completely gone over the line, but before your player begins to celebrate, pause game play and watch the replay. Every time you watch the replay, an extra goal will added to your score.

Note: It is not necessary to watch the entire replay to get a goal added. Simply select "Replay" then immediately return to the main menu. This saves a lots of time and goals. If you do this in master league, then the goal bonus at the end of the match can be huge (aim for about 200 goals).
