With the right orders you can use every Formation. with 4 defenders there are 4 Players that can mark 3 attackers! you only have to use zonal marking. Butterfly will work very well, but 4-5-1 v, 4-3-2w-1 or 4-4-2 it will work too.
on the other way, i will beat all this formations with 3-4-3. u only have to use the right orders!
