Formations after UPDATE

[Toxcatl]

I have no idea tbh. It is possible to say if he plays defensive though, so I just assume that it goes with counter-attacks. I usually choose tactics using this rock-paper-scissors system: Attack > Possession > Defence > Attack... It is not a science, I have no idea if it's right or not. There are too many other factors in play.
As for High pressing and m2m, I just don't care when I choose my passing. If I have low % of completed passes or need def/possession, I set Short. If I have high % or need attack, I set Long. After that I just watch how the new orders change the statistics (passes, shots) and react accordingly.

If I have better stats, I do nothing. Even if I'm attacking and leading, and current score suits me just fine. Do not fix what's not broken. Many times I switched from attacking tactics to defending, and everything went to hell. It looks like my attackers keep their team occupied, and if I reduce my attacking efforts, that lets them to play the game as they want it.
Or maybe this is just my delusions.
