Here's mine for those interested...
For teams who are 1 star (or more) worse than my team, I set the difficulty to PRO (though you could substitute this with WORLD CLASS) and use semi controls (with manual through balls). For every other team, I set the difficulty to LEGENDARY, with assisted controls (except for through balls - manual, and crossing - semi).
I use slow speed on PRO, and normal speed on (WORLD CLASS and) LEGENDARY. All are set to eight minute half lengths.
Slider / Player / CPU
Sprint 50/48 (prevents certain AI passes being successful)
Acceleration 50/49 (prevents certain AI passes being successful)
Shot Error 50/54
Pass Error 50/59 (any higher and crosses break)
Shot Speed 50/49
Pass Speed 50/36 (causes more AI mistakes than pass error does)
Injury Freq 62/62
Injury Severity 42/42
GK Ability 28/28 (any lower and easy shots get pushed away)
Marking 50/45 (stops an AI interception cheat where the defender moves *through* your striker to regain possession)
Run Frequency 34/50 (keeps AI moving the ball forward, helps prevent overly possessive play)
Line Height 58/58
Line Length 50/60 (causes larger pass distances and introduces error)
Line Width 50/60 (prevents CPU packing the middle whilst allowing team tactics to work as expected)
Fullbacks 55/55
Powerbar 52 (to keep relative parity with online play)
First Touch 50/65 (prevents AI cheating)
If PRO seems too easy, reset the CPU's sprint/acceleration/first touch, reduce shooting, passing error and first touch to 40, and increase the marking to 60.
