About 3 months ago, the asso groups I had with my 2 teams played in the same tournament and NIK (from khris group) played vs my reserves, ManU (of madflo group).
So I had the chance to make some observations in "official" games.
In the first game, I set in one team hard tackling and in the other easy tackling.
Absolutely no difference in the game play.
I tried to find some hints for those choices of mine, but no.
In the second leg of the tournament, as NIK won the first game with 2-0, I tried to help a little ManU so to have equal points.
So I set some abnormal orders in NIK
Defense, no counters, easy tackling, off-side trap, man to man mix pass, from the middle (but having AML-AMR in the team).
Couldn't observe anything about orders, NIK won again
