I started using this formation after placing 2nd in both Seasons 1 & 2 using 3-2-2-1-2 formation.
Presently in Season 3, although I planned on using 4-2-3-1, I'm using 4-1-3-2 wide because my other DMC is injured... And I'm glad he did!

I'm doing very well in my league and Champions League. (I score an average of 3 goals in every match although I concede as well).

I use
Mentality: Attacking.
Passing: mixed.
Pressing: own half.
Tackling: normal.
Focus: mixed.
Marking: zonal.
Counter Attack: Yes.

Also, I put Red arrows on my 2ST or 1AMC & 1ST( when my other striker is injured); and blue arrows on GK, 2DCs & DMC.

Good luck! I hope this helps.
