Hello, today I am going to face 4-3-3 flat:

- ST ST ST -
- -- --------
--MC MC MC--
--------------
DL DC --DC--DR

I am thinking of using this formation:

------ST------
AML--------AMR
--MC-MC-MC---
---------------
DL-DC---DC-DR

My idea is like that. Since he has 3x ST I am using 4 defenders to cover his ST.
Then since he has 3x MC I am using 3x MC on the same spots, so that they are covered aswell.
Now since he only has DC ( central defenders ) I am planning to use AML and AMR and focus passing down both flanks. He has neither DL / DR nor DMR/DML so my AML/AMR will remain uncovered.
I will use this orders:
Attacking
Down both flanks
Own Half
Hard tackling ( he has no free kick specialist/my players have high moral/his quality of players is way better than mine)
Passing Style: Short
Marking: Zonal
No counter attacks, no offside traps.

What do you guys think I can change for better results?
