I would try this tactic out which was popular. I changed the striker to Advanced Forward and added BPDs. You can tweak it to have slightly less possession as well.

Hi Knap.
Following on from the Argus formation, it seems the AI is using the 3421 formation a lot more now e.g.
GK
CB CB CB
WB DM DM WB
IF AF IF
Would you be able to create a tactic in this shape or have you previously?
