if there would be a winning formation then most player would play it just to win
i would prefer a strong formation that is often played like 4-5-1 V or 4-4-2 classic. Maybe then you get best chances.
But i dont really understand why someone plays a manager if he wanna do nothing for it
Both formations are easily beaten with the butterfly, i faced 4-5-1V and 4-4-2 so many times this season and never lost/draw against it.
But i dont see many teams playing 3-2-2-2-1 butterfly, maybe you've got a point there
