Total Club Manager 2005 - Platform: XBox

Easy money:
-----------
Go into Club/Stadium Facilities/Stadium Expansion. Change the stadium type 
(rounded corners, oval; this will cost you money) and select "Build Stadium". Do 
this again (changing the stadium type, build it), and you will receive money. 

Note: Do not do this if you are thinking about building a new stadium.

Morale:
-------
Always check the player status screen before you sell a player. If a player has 
a close friend on the team, this will cost a lot of morale. This could be 
disastrous if the remaining player is one of your stars.
