I think you must go technical and then passing long bullet throw.I play offline and i use original tactic not tweaked.You just need right players to make this tactic work.
Both CWB must have "long flat throw" or long throw stat 16+ so you can train them for flat bullet throw.i have 4 players with that stat trained Jonathan Silva,Tin Jedvaj,Chambers and Digne,two for each side so i can rotate.
This tactic is insane people who say it dont lie or dont have players for this tactic.Here are my results won all,only 1 defeat and 5 draws(2 in premiere league) GD insane +235.Scored 272 goals conceded 37.
