Table of Counter Formations v2.0 - Which formation to use?

Countering opponent's formation xD

[Kvelend]

Hey guys, I'm playing tomorrow against a better team than mine for CL groups. (99% 55.0, to my 90% 52.7)

His formation is 3313 (all narrow), which is very similar to a 343 or even more to the 31213 showing on the list.

For the latter 413w2 or 451 diamond are advised, and against the first 4321, 442, 352 are the counters propones.

But since he is not using either, I wanted yo ask if there was a appropriate formation to counter that.

Or how can you tell where to put your players to actually counter other peoples squads.

If he is all narrow, should I widen my squad?

Or is it ok to be defensive with low pressure against a better team?

Or where do you draw the line.. at 10% better, 20%, more? Thanks!
