not neccesarily
you can use it also with that formation too.
Also with 4-4-2 ND or classic.

The form is around 7+
that's descent rate for a defender or MC but not for a winger. Your AML-AMR-AMC must have 8 avg. and scoring.

vs 4-1-2-1-2 ND usually I play with 3DC-1DMC-3MC-AML-AMR-ST
vs 4-5-1V DL-DC-DR-2DMC-2MC-AML-AMR-ST
Those are my started squads, then during the game, maybe change them.
