Tested this on my Roma save, and it worked a treat! Started badly though, conceded in the first game after 3 mins, and I was a bit apprehensive, but I noticed greater fluency in movement and passing(compared to other tactics I've used) so I saw the positives. In the end I comprehensively won, at Fiorentina... AWAY!
So far played bout 10 or so games, and I haven't yet lost, most notable victory was at Inter, where they got spanked 4-0. I've conceded 2 goals against for bout 15+. And like you said, you don't have to do nothing -- no o.i, match prep or even touchline shouts. I don't have a Citeh-esque All-star team (yet), but with the right players, this tactic is the dog's bollocks. Good offensively,defensively. Even corners ain't bad, haven't been bangin' them in mind, but a vast improvement over other tactics I've used. I haven't touched anything, and it fit perfectly in my team. The only thing I might add that may have contributed to the run of good results could be that my previous tactic was a similar formation.
All in all, Ace tactic mate!
A good Plug n play tactic if you're looking for one! Great work dude!(H)
