thanks for the answer !!!
by the way, about legacy defending (one button your player instead of 2 in tactical defending which I'm using until now), I tested one game with this type of defense and it changes a lot the position of players on the field.
I don't know if it's my imagination or not but in tactical, you press the opponent but you can still move your player a bit to the right or left which is not the case in legacy defending where it runs to the oppenent in order to tackle him. Moreover, this slightly moves right or left enable cpu to pass easier.
So my question is, does your sliders better suit for tactical or legacy defending (in general) or is it only your personnal pref?
