Ok so i was searching for a tactic for fm20 and literally i found nothing that i like. The tactics that work on the match engine seemed a bit not realistic so i tried to make one of my own. I saw that 4-4-2 actually works great but because i don't really like it i made this asymmetric one. Don't have any results to post yet because I'm currently on the preseason with with Torino in Serie A but I've seen some good stats so far (i'll try to keep posting results as the season goes on).
If you like it post your own results or even your thoughts on the tactic.
PS: The only PI i use are on the DCL: stay wider and on DR: stay narrower
