At the editor, to change the team and management data, open the "Tmdata" or "Mgdata" databases and edit them. You can give a team lots of money by going to "Cash" and entering a number up to 50,000. Note: This will change to 50 million during game play.
At "Manger Info", select "Add More Managers". Choose the country and when asked to type in a manger's name, type in the real coach's name. For example, with England enter Glenn Hoddle and for The Netherlands enter Guus Hiddink.
At the editor, open the "Players" database, then select "Edit Database" and enter "Players". Click on a player. You can now set all his ratings up to "20". When done, begin a new game and the player will be a top class footballer. You can also create new players.
Add managers to the team from which you want to purchase a player. Place that player on the transfer list, then retire from the club and purchase that player. Note: This can only be done with clubs that are in your league.
