A question for players on high lvl... How do you think about "counter formations"?

[Tactician]

3-5-2V or 4-5-1V.
I'll go 3-5-2V thru flanks, attacking, short passing, hard, whole pitch, no counter, no offside, zonal

but depends on strenght of teams

I faced this advanced diamond formation twice so far against the same opponent. The opponent is of lower quality, but he caused a lot of problems. He scored 5 goals in the two matches combined. He scored 2 goals in 1 match despite playing with one man less for about one half.
