i use the 3-3-3-1 Guardiola (beta), the first one on the original post.
i played all this save on 15.3.1.
Put the tactic in all slots, change the mentality in two of them.
Counter in one and Attack in other, so you'll have one tactic in control, other in counter and another in attack,
This is how i start the games:
I only use the attack in HOME against weaker teams, when i know they'll defend in entire match.
Counter i use away against bigger teams, like chelsea, manchester, real madrid.
but during the match i change the mentality depending of how my team are playing.
Your assistant give opposition instructions, so he need a good tactical knowledge
(I Don't know how much this is important, if the OI's in OP are better or worse)
Trainings are team cohesion, sometimes i change to balanced
during the season trainings are always on avarage.
match prep defending positions like in OP, sometimes i change match prep to offensive positions or teamwork,
always on 40%.
