i was joking in my previous reply,

you can use whatever formation you like and it not just about formation, it about how you order each of your plyer either to move forward or backwack or just stay in the position,

and the effectiveness is depends on how your opponent order their player too, and player quality or in match performance rate

so if you order your player to attack at the area which your opponent stronger at that area, you will facing hard time to score,

if you not send enough player to protect the area that your opponent strong in attack, you will easily concede
