In my opinion the issue has two different solutions strictly related to the causes of the issue:
- the playing style are "ready" for the player, IMHO the best way to implement different "difficult levels" could be to have the same game for everyone, but for advanced users willing to have it, the possibility to go deep with tactic design. Now you click on Gegenpress and you have your players pressing in a certain way, as default, if the triggers of pressing, attacking movements without ball etc should be closed by ourselves instead, the game would become immediately more deep and challenging. This is just an example.
- for the particular case, it could help also a fine tuning of the weight of physical attributes vs weight of mental and technical attributes. With a perfect balance, every playing style would have its pros and cons.
