3-1 WIN.
Thanks to all that commented on the earlier thread when I posted that narrow diamond is not working vs 4-4-2 classic anymore. It inspired me enough to go 3N-0-4-1-2, attacking, mixed attack, whole pitch, normal tackle, mixed passing, zonal with no counter, no offsides. (info for those who want it for future use.)
I wonder if 3-4-1-2 is the new narrow diamond v 4-4-2?
