I use my DoF like this:
My DoF is not assigned any tasks.
If I want to buy a player I add him to the list.
If I want to sell/loan a player I add him to the list and he sorts it out.
Other than that He just sits there...waiting. (because if I give him stuff to do like look for players he drives me crazy) :@

What got me thinking was I used my DoF to sign Stevan Jovetic, the scouts indicated he would want about £90k to £120k per week which was within my budget so I added him and the DoF got to work.
As i have final say so on contracts I was shocked buy what I was met with:

1. $180k per week
2. Goal bonus £18k
3. Appearance fee £18k
4. Team of the year £700k
5. Top goal scorer £900k

My DoF's name was Damien Comolli:

So needless to say I didn't sign Stevan Jovetic, I did something i never do and that is reload. :-/
I also fired up Genie Scout to look closer at staff attributes and found two interesting ones:
So forsaking all the main attributes associated with DoF's I signed this dude as my DoF Simeon Velinov

1. Buying players (19)
   
2. Hardness of trading (17)

and repeated my attempt to sign Jovetic and this was the result:

1. $125k per week
2. Relegation wage drop 25%
3. Goal bonus £12.5k
4. Appearance fee £12.5k
5. Team of the year £500k
6. Top goal scorer £625k

• £55k per week cheaper
  
• 25% wage drop if relegated
• £5.5k less to pay per goal
• £5.5k less to pay per appearance
• £200k saved if he makes team of year
  
• £275k saved if he gets golden boot.

Simeon Velinov's main attributes are really bad for a top flight club to even consider employing him but every time (in the limited tests I have run) he gets a better deal than so called top flight DoF's.
The smaller the deal the smaller the savings but potentially huge deals like for Falcao could save a bundle.
