hey mates,i've been thinking about using this tactic with my ajax squad,but i'm out of time to play FM in this week. I've been reading the posts though,and it seems to me that the tactic results have too much variability.I think it's something to be expected as it is a very specific tactic.
Anyway, have you thought that the problem isn't the tactic,but the players? i mean,if it's working wonders for some,and **** for others,what is changing majorly is the players(assuming the factor between the chair and the PC will play the tactic correctly as instructed). My opinion is that you must have fast defenders(height above 1,80 is satisfactory) and/or really high mentals to set up a good defense,and all the other players who defend must have high teamwork and work rate(stamina also for fullbacks). Basically what i'm saying is to set up a team that the players in the middle of the pitch must be wise,and in the flanks must be hardworking.When i finally managed to do this with my squad,it improved from an average of 1,1 goals against per game to 0,6 in the league.
Cheers,looking foward to more results and to test it myself!
