Sorry i didn't see your post except now so you will find you answer at the 1st page
4-3-3
This formation has a fatal flaw in the form of not having any wingers. To beat it, exploit this major weakness by focusing your attack on the flanks while defending your middle. Here's a few examples of formations that do exactly that:
3-1-3-2-1
----------ST----------
(UP)--------------AMR(UP)
----MC--MC--MC----
---------DMC(UP)---------
----DC--DC--DC-----
4-1-4-1
----------------ST--------------
---------------------------------
ML (UP)--MC----MC----MR (UP)
--------------DMC (UP)-------
DL (UP)--DC--DC------DR (UP)
3-3-2-2
--------ST----ST-----
(UP)--------------AMR(UP)
----MC--MC--MC----
-----------------------
----DC--DC--DC----
The exact formation is up to you, but keep this in mind:
a) Always attack the flanks with either ML/MR with red arrows or AML/AMR
b)Use at least 2 DC's
c)Use at least 2 MC's
d)The combined number of your Defenders+DMC's+MC's must be 6 or higher.
e) MC's+ML/MR must be 4 or higher.
Tactics against 4-3-3.
4-3-3 is an attacking formation, so you can either play offside trap with very fast defenders while pressing the whole pitch, or a more defensive counter-attacking way while pressing your own half.
Most formations able to easily beat 4-3-3 will be heavy in the midfield, as such, use short passing if playing offensively and mixed passing when trying to counter attack.
