Table of Counter Formations - What to use?

[SSDD]

my formation is : 4-5-1 V style

opponent formation : 3N-1-3W-2(AMC)-1ST

What about orders and arrows ?

Well, your opponent's using 2 AMC, so your DMC will really need all the help he can get. Which means a blue arrow on at least one of yor MC's, maybe even both. This is the main thing, other than attacking the flanks (he's fielding only DC's).
So: normal mentality, passing down both flanks, pressing own half, normal tackling, mixed passing and zonal marking. Red arrows on your wide players, blue on your CM's. No arrows on your DMC.
Also: you can put blue arrows on you CD (I do, most of the time) and if you're the underdog, you can use defensive mentality, long passes and counter-attacks.
This is what i would do, still, this game's engine is a really weird one. Sometimes it generates really random sh*t, so everything's possible.
GL!
