I am unable to share my tactics and instructions as i change them based on my opponent and also depends on game statistics.
I can share my formation strategies instead as it is less opponent dependant.
My formation changes every season and depends on the fast trainer i am able to buy to fill gaps.
But in general i feel safer following these guidelines below.
Min 3 defenders
Either 3 DCs or 2 wingbacks and a DC
Min 4 in central midfield area
Either 2 DMC or 2 MC and an AMC
My attackers are fixed. Always 2 wingers and an AMC as well at an ST.
