Little update since I've had a lot of spare time today:
Decided on testing testing with Burnley and they're pretty much ripping the Championship apart. Not as many goals as I would've liked (average 2 - 3 a game, mind), but I haven't lost in 18 games after a rocky start (3 wins, 4 draws and 2 defeats, then turned adjusted match preparation to defensive positioning and then it worked wonders for me) and my Central Midfielders are averaging 40 - 55 passes completed each game.
Excellent work on making such an effective tactic.
edit: lol, I was about to take some screenshots and realised I accidentally overwritten the save with another game to test another tactic. Sorry. :/
