I'm sharing the tactic that uses two libero's as centre-backs. This tactic is more suited for mid or better teams. I did not test it with the smaller teams, let me know how it goes if you do.
If you are playing as a top club changing the mentality to Attaking might yield even better results.
OI's are left for AM.
In case of red card remove the striker. I recommend putting left footed striker as leftAF and right footed as rightAF. Make them swap positions during the game too.
Train everyone to their respective positions.
Let me know how the tactic works for you
