Mr. Rayo
I really want to see a 4-2-3-1 tactic do great, so I tweaked the “424 deformation” tactic by A Smile.
Tweaks I made:
Positions - the left AF was changed to a SS (with same instructions as the original SS) and the original SS was changed to an IF on the right (with same instructions as the left IF)
In possession I added focus play down the right and overlap left (focus play down both flanks and overlap both sides)
