Good players for free:
Take over a team with good players. Keep fining them for no reason to make them unhappy. 
Then, use your normal club to bid whatever amount of money for them and offer them a decent wage. 
Wait until the transfer has gone through, then retire from that team. Note: 
Players such as Ronaldo, Raul, Henry will not want to go to lower achieving teams.

Easy money:
When December 31st comes round each year, you can get players free in June. 
If you want easy money, get players that you do not really want 
then get them on a free only if you know that clubs would be interested in him. 
Then, sell him when you get him on free. Take over a team as you normally would. 
If their finances are not very good, then take over a rich team like Chelsea, Real Madrid etc. 
as well as your normal team. Bid over the odds prices for your unneeded players. 
Stay as the manager until the transfer goes through, then retire. 
Your first team will now have high finances.

Low budget players:
If you have a low budget like (2,3)million then 
try and buy paul ifill and vassilis tsiartas 
(on the free transfers)

Buy these players:
If you buy the following players, then you stand a good chance of winning your league. 
I had all of these players in my squad and I did the domestic treble, and now, in season 2, 
I have already retained my premiership, and league cup titles.

Van der Sar - GK
Panucci - DR
Boa Morte - AM L/C
Malbranque - AM L/R
Ortega - SC
Diop - DMC
Gravesen - MC
Figo - AML/R

Total spending for these stars will be under 30m.


Always win big:
When the fixtures screen appears before a match, find out who you are playing and add them as a manager. 
When it is time, set all their players in bad positions (for example, forward as the goalkeeper). 
Put all their players out wide and play your formation down the middle. 
You will win about 30-0 every time. This works well for lower league clubs trying to get up.

Take over as England manager:
To take over early in the game as England manager, add a user to manage a national team. 
Select England, then retire instantly. Next, go back to your normal team and apply for the job. 
This saves waiting for Sven to retire. You need a good rating or Big Sam will get the position.

Killer Keepers:
Buy Michael Rensing from Bayern and Jan Lastuvka from Shakhtar these are some killer keepers!
