This tactic is fantastic, i am playing with Croatian champions Dinamo, and I'm 2nd in champions league group stage, just 1 point behind ManU, and the best thing is that i bought only 1 player (Agustin Delgado - strong targetman). P.S. Played 11 league games, and concided only 1 goal while scoring 32
The AI is not cracking tactics, just try the tweaks fuss mentioned, change your teamtalks or player interactions and it should be fine. BTW: I am using v1 and it is the one for me, tryed all the other versions but only V1 works for my team.
