As I was involved a bit in the original discussion, I thought I'd take a quick look at where you have got to - and you've come a long way, great job
.
I downloaded the tactic and had a quick play using my Real Madrid team. There certainly is a lot of possession, and what you have done with the Inside Forwards is pretty interesting. I like that.
The only issue I had was defensively. Playing so wide, with such a high defensive line and playing offside really exposed me to pacey strikers as I found out against Spurs who destroyed me 4-0. Their forwards had huge amounts of space to run into and we lost 3 goals due to this.
Obviously you have had a lot of success with the tactic, so credit for that
. For my team, personally I would make it much more narrow (which may also help passing between the front 4) and drop the defensive line back 3 or 4 clicks. I'd probably also change the covering CB or drop the offside trap as a covering CB can cause issues when trying to play offside.
Anyway, good job to you for coming so far and getting success !
